- Fixed possible crash when you import EPS file.

- If you defined the "COAT_FSERVER" environment variable then usual licensing will not work, only local network/fserver will be the source of the license. So, if by some reason license does not work, please check if this variable is not declared or if declared - it should be declared correctly, as the server_ip:port.

- Fixed the vertex PBR export problem (strange grid) when you export from the voxel mode to Blender via AppLink (in surface mode it worked correctly).

- There is option "Accurate triangles" in auto-export dialog to choose the triangulation style. Also, you may choose the exact export polycount there (as well as in the retopo via decimation).

- Fixed FBX import problem (scale was broken if there are multiple objects), it is especially important for the Blender AppLink.

- The objects with sharp edges (split normals) correctly loaded into the sculpt room, tiny edge created to keep it sharp.

- Retopo/Modeling Room: Option "Relax Sharp Edges" is added

- The render access via the Python, scripted access to render may be very helpful, example included.

- Retopo-> Mesh-> Take mesh from paint room correctly takes objects list as well. Also taking Paint mesh by Python also works correctly.

- Fixed Undo problem when you do multiple copies of the masked layer

- Non-destructive text/curves/picture tools in the paint toolset, now each layer keeps the text/picture/curve setting if applied over the layer. The corresponding icon displayed over the layer.

- 3DCoat tries to locate and update AppLinks even if multiple versions of Blender installed. Also, all install paths maybe checked with python: print(coat.io.listBlenderInstallFolders())

- The paint conditions thumbnail correctly shown in sculpt room, the freeze preview uses gray color, not the current color.

- Python: utils.set, utils.get, menu_item(...) may create menu items that directly execute some script via id = '$execute:path/to/script.py'.

- Possibility to add own, completely custom, room-dependent menu (with usual commands, scripts, addons, info and other). It is near the navigation icon.

- New unique possiblity of the 3DCoat! The PPP scene with the normalmap name be converted into the true sculpt geometry using the Painting room, `Bake->PaintMath to Sculpt`. So, the reverse workflow is now possible, when you have normal map over the lowpoly mesh, you may get the highpoly source, deeply re-make it and then bake again. For example, you have AI generated rough prototype, you may import into Coat for PPP, then convert to sculpt, re-make it, add details.

- Fixing the difficulty to drag & drop 3DCoat.app bundle under macOS

- Fixed problems with fill when you import ppp mesh with "Triangulation" turned ON.

- Better support of Python in rooms customization, now Python may be used to create the menu, navigation, toolset, rmb actions instead of cpp.

- The essential update of the Blender App Link: (1) Sculpt mesh may be dropped directly to Blender with vertex color, roughness and metallicity. The corresponding nodes structure created. (2) The scale correctly preserved when you pass the mesh between 3DCoat and Blender. (3) Blender may drop sculpt mesh to 3DCoat with vertex color.

- Sculpt Room: tool "Replicator" - Option added "Objects merge as Boolean"

- Nurbs Room: A new tool "Ruled Surface" Added

- "File->Import->Import for vertex painting" may recover the geometry from the normalmap over the mesh. Also, mesh may be additionally subdivided if it's density is less than the texture density. So, it opens new workflow: say, you used some service (say AI service) to make a prototype, then imported it to 3DCao, detailed it with texture (applying non-trivial topolgy changes if need). Also, the "Painting->Bake" menu actions cleaned for good understanding what it does.

- Retopo/Modeling Room: InSet Tool - Bug fixed

It simplifies the scripts development a lot! Soon it will transform into the complete actions recorder (as soon as all actions will be captured).

- Fixed problem in Transform tool when you can't unselect the current volume among several selected with CTRL and rectangle.

- Masks improvements: Layers->Copy channels includes copy to mask layer; "Invert mask" in RMB menu over the mask. Also, each layer (non-masked) may be assigned as the mask for another layer. And the mask layer may be separated just as regular layer (it will stop the masking for the parent layer). All that functionality included into the Python API.

- Fixed problem with "Slide edges": Sliding vertices now snap correctly when moving along an edge loop.

- Fixed problem when after the File->Open the filename does not appear in the header.

- The AI knowledge database is completely automated, updating whenever any text changes or a new tool appears, as soon as a valid hint is provided. Additionally, all new functions in the Python API automatically appear in the AI database.

- Sculpt Room: tool "Multiple objects" - the Jitter is improved. The position of the model on the surface has been improved.

- User-friendly and pretty hints when you make the scripts with the Python API (.pyi files syntax updated).

- If you start to paint over the island in the UV window with a steady stroke, then move out of the island to the empty space, the stroke continues correctly.

- Fixed crash in Autoexport python example

- The material preview window may be permanently closed, if you want to restore, go to Edit -> Preferences -> Viewport -> Hide material thumbnail

- UI visual corrections: bigger header and close button for undocked panels (like tool parameters), menu headers.

- The eraser acts in Rect/lasso mode with the CTRL key in paint tools if the depth channel is disabled, similar to regular paint tools.

- PPP texturing speed improvements, it is especially visible on huge resolution (8-16K), when you change whole layer (like opacity) or essential part of the layer (big brush).

- Pyton API: coat.ui.highlight, enablePenChannel, isEnabledPenChannel

- Crash reports fixed (actually not many there)

- In the transform/instance tools the rectangle/lasso selection allowed - it selects objects within the area, CTRL/SHIFT modifiers allowed.

- Fixed problem of the UV set name change

- Fixed fonts issue in 3DCoat Textura/Print

- The knowledge about all UI elements in 3DCoat included into the AI database, it makes it much smarter.

- In 3DCoat 2024 the default location of documents changed to User/Documents/3DCoat/. Previously, if OneDrive installed it was the default documents: User/OneDrive/Documents/3DCoat. It caused multiple problems and strange bugs due to files locking, failed attempts to sync with the cloud. User files and license copied to the new location automatically. If you don't use OneDrive nothing changes for you.

- Fixed contradiction between vertical Activity bar and all right panels - now it is impossible to activate items from activity bar when you move mouse toward the panels docked at the right. It activates windows only when you hover and stop the mouse over the activity item.

- Fixed retopo/modeling problems arisen in the 41 build.

- A workaround for a problem: "Under new macOS Sonoma, an input string dialog overlays the whole window."

- Fixed essential problem of cutoff + new curves that was causing the edge artifacts. Now cutoff with curves is clean. Also, Ut off tool got checkbox [x] Use intersection. This is for convenience, if you need intersection instead of subtraction. It was possible using SHIFT, but now it is possible via UI as well.

- The super important and long-waited tool Edit->Scene scale master

- Blender AppLink problems fixed (when you bring model Blender -> 3DCoat)

- Fixed Import Quixel assets if the zip has sub-folders.

- Very essential Python/Core API update: retopo/modeling room represented in API. Fully procedural lowpoly modeling now possible. See the documentation and examples. Some retopo/modeling problems fixed as well.

- Fixed super longstanding and rare saving scene saving issue (related to ptex/microvertex painting) that leads to the scene file corruption.

- Fixed (possible) long nasty spikes problem for live booleans in some cases when intersecting surfaces has planar intersections.

- Fixed broken CoreAPI compiling, I also made additional automated tests to prevent this situation (second attempt, I hope final).

- Licensing of updates has been liberated a bit: prevented the situation when upgrades expire (due to license terms) and you can't use beta upgrades because you can't pay for them (because betas are not in downloads). Now in this case, betas may be used until the stable build is released.

- If Blender installed not into the default folder, 3DCoat will find it anyway and update the App Link.

- Fixed problem when deleting the volume that partcipates in booleans does not refresh the booleans scene correctly.

- Fixed problems related to File->Import->Import multiple objects (broken scene, impossible to import scene as part of files list)

- Fixed problems related to voxel hide: Res+, Resample, etc. do not destroy hide undo. Res+ unhides (with undo) and applies the resolution increase. Undo restores to unhidden state; the next undo restores the hidden state. Also, unhide hotkey is not hardcoded as before.

- Fixed problems related to importing some EPS files.

- Fixed problems related to per-triangle hide tool (in surface and voxels), now it compatible with LB.

- Now Blender AppLink supports both Blender 3.x and Blender 4.x. Pay attention, AppLinks for the 3rd and 4th versions of Blender are different. Generally, all that you need is to agree with 3DCoat to copy files. If Blender installed into the default path the AppLinks will be updated automatically.

- Reviewed all recent automated crash reports, fixed every possible unsafe code.

- Correct "Retopo via decimation" with Live Booleans. Python API volume->decimated mesh functions extended.

- Pose tool in pen mode works correctly when "Through all volumes" is turned off.

- Python projects with multiple modules supported. PY files in same folder as the main script may be imported.

- Better Python projects management - If you try to edit the separate PY file Coat offers project creation. Opening project leads to .pyi file update. The .pyi file contains the 3DCoat's API syntax scheme for the VS Code. The launch.json created automatically to be able to debug scripts step-by-step.

- The VoxExtrude tool works natively in voxels as well, it opens up a workflow: use VoxHide to hide some parts, then use VoxExtrude, then unhide. Previously, this sequence was causing mesh destruction.

- Scripts may now operate if the 3DCoat's window minimized.

- The Python debugging via the Visual Studio Code is now possible, see the Python documentation.

- The chosen font for text/primitive tools kept between 3dCoat sessions.

- Correct size for the layer/sculpt tree rename controls.

- Better visibility for measure tool numbers

- Fixed incorrect "rename" function for sculpt tree elements in python API.

- Python issues fixed (cluttering with 32/64 bit environment that was preventing the packages installation)

- Correct export for 3d printing with live booleans. Merge visible/subtree to surface/voxels works correctly as well.

- Toggle ghosted works a bit more smartly: if object picked, it toggles ghosting only for that object, otherwise it toggles all selected objects.

- Click over LB icon disables it (to view object as is), RMB shows the quick menu to change the boolean operation type.

- Fixed broken flat shade/relief/gloss/... only views for the sculpt objects.

- Live booleans enabled by default.

- Very essential optimization of live booleans speed. On my PC scene with 30m + 8m, subtraction, we move transform gizmo of smaller object, the FPS is 11-12.

- Merge visible/Merge subtree work correctly with the Live booleans.

- Live Booleans moved to own section in the RMB menu.

- Live booleans may be correctly bound to hotkeys.

- Menu/rooms scripts in UserPrefs/Rooms/ may now be written on Python. The .py files acceptable instead of .cpp, you may use python syntax and same functions names.

- If you ghost the volume that participates in live booleans, it becomes visible (but still cuts the parent). This way you may see and sculpt it (enabling ghost picking & acting).

- Restored missing commands in Sculpt->Coat tool (fill curve with patch): create retopo patch, create retopo quad patch, create doublesided retopo mesh.

- Fixed problems with 16 bit integer tiffs Alphas import. In alphas panel, there is new option - "Positive alpha" that means "If enabled, the top left pixel value will not be subtracted from the alpha depth."

- Fixed occasional crash when double-clicking on the viewport after the "3DCoat" startup

- Fixed live booleans problem when hiding volume leaves hole in the parent.

- Additional self-test mechanism to prevent situations when CoreAPI gets failed into the build. Also, any script may be executed as 3DCoat.exe -script "path to cpp/python script". The script may do some action and exit using coat::utils::quit() / coat.utils.quit()

- Baking supported for Live booleans.

- Access to live booleans via the python/CoreAPI.

- Live booleans now work correctly during any sculpt changes, just on-the-fly, also the collapsing to regular mesh available via RMB->Collapse boolean tree.

- Live booleans essentially updated: any complex hierarchical boolean combinations allowed, union support, correct work with instances (instances may not work with LB, but at least instancing stops if booleans are used). Correct picking, so retopo is possible. Correct painting over boolean volumes.

- Several symmetry - related UI issues fixed.

- Cloth tool improvements: if you turn current volume to cloth, you may ghost or hide the volume to avoid collision of the mesh with the volume.

- Little (but important) improvement of the Bas-relief tool if you use "Extrude free edges": the possibility to relax open edges before the extrusion.

- Undo for live booleans, Union as one of live boolean operations.

- Fixed Blob tool problem when the small loops was not filled.

- Warning! This build is not digitally signed due to delay in delivering the dongle for signing to Ukraine. This is not a problem to users that use updater, but may look suspicious to new users that use installer. So if you see the warning in Windows, just ignore it and continue.

- Freeze/Un-freeze/Paint/Erase as additional modifiers in SHIFT/CTRL-SHIFT actions.

- Possibility to relax the edges of holes in the surface mode.

- Fixed problem when arrays (repeating shapes/lasso in E mode) was not working correctly in "On plane" mode over transformed volumes.

- First release of the Live Booleans. It is in development stage; this is essentially beta. Enable it in Preferences > Beta > Live Booleans; look at the usage hint there. At its current stage, it works only with voxel volumes, but the intersection is sharp. No bevel (but this will be done later). In the scene, you will see a preview; small, narrow holes are possible, but the exported mesh is watertight.

- Scripting updated, better ui commands sequence execution algorithm, now if referred control is absent, the script waits short time for appearance. Access to settings. Fixed problem when some tool parameters can't be changed.

- Gizmo problems fixed: strange colors of gizmo in aces tone-mapping, scale/rotate buttons in retopo/modeling.

- Fixed artifacts on the edge of rect/lasso/shape selection in surface sculpting in any sculpt brush.

- Several users experienced problems with sliders, this is corrected.

- Fixed holes problem when you use Auto-subdivide in Brush Engine near the freeze border.

- In Prefs->Tools you may chose what keys combination will be used for E-mode arrays and shape rounding: NONE/CTRL/SHIFT, 0..9, R

- Speed improvements for the retopo/modeling toolset (multithreading whenever possible), especially for bigger polycount.

- Fixed surface brushing problem (holes in some cases, freeze state flickering).

- Copy clay correctly works in voxel toolset (it auto-turns to surface to prevent mesh destruction)

- Better quality of auto-mapping, less amount of islands, more accurate shape of each island.

- Correct work with complex N-gons for paint/retopo/uv tools, auto-mappping supports complex "bad" meshes with long triangles and polygons, it will not hang over very complex geometry (time to optimize limited).

- Fixed factures problem when the vertex color vanished even if factures layer is invisible.

- Fixed the sculpt/freeze/paint mode with symmetry.

- If you change slider value under low fps the result was almost uncontrollable, now that is fixed.

- "Emboss bower" in layers settings works correctly for PPP.

- The overall performance of 3DCaot greatly improved due to additional multi-threading optimizations. This is especially visible for per-pixel painting. Switching layers visibility, changing overall opacity become faster (approximately) 3 times.

- Fixed rare problem of random spots over the surface in voxel tools (brushing, primitives). This fix also resulted in some speedup of the voxel sculpting using the voxel brush engine.

- Modeling Room: Align Vertices. Improvement of Alignment by Plane. You can edit the shift of the Plane.

- Tool Smart Extrude: added Mode - Multi Extrude

- Fixed problem of "Apply UV" in UV room - if you use it and the go to Paint room and apply UV-s again - the texture becomes screwed.

- Fixed problem when Sculpt Clone/Cut&Clone produces meshes with holed if bevel enabled.

- Fixed problem of recalling the freeze state from the layer (relall pose selection from layer worked correctly, but recalling the freeze - not)

- In some cases the blob tool may work too long time (big shot square, randomly incorrect orientation, big volume density). In the case the warning appears. But even after warning it was hanging too long. Now after warning it stops operation quickly.

- In "On plane" mode the wheel (or CTRL Wheel) may optionally be used to move the plane back and forward.

- "Import tiles as UV-sets" works for MV painting as well.

- Fixed hang in render tool when the light intensity of one light source is zero.

- Fixed possible problem when user sets 16x AA in AO/Cavity calculation routine, but it is impossible to use because it requires too much video memory. In this case AA value reduced.

- Fixed crash in "Sweep profile along guide curve".

- Fixed crash in "Sweep profile along guide curve".

- Modeling Room: AlignmentVertexs- Alignment by Plane Orthogonal to Normal is implemented. Undo is improved

- Fixed possible instability in AO calculation routine.

- Molding operations and VDM creation included into the Python API.

- Fixed the problem of scene parent changing in the Python scripts.

- Retopo/Modeling Room: Improvement of tool Select. Selecting islands of faces with similar normals. Using Ctrl + on the Number pad.

- The Alpha from 3D model creation dialog updated - better UI, possibility to create VDM alpha from the arbitrary 3D model. Of course VDM-s have some limitations, it is like thin film deformation and wrapping around the object, it is not always topologically possible.

- Retopo/Modeling Room: Improvement of Select FreeLasso (edges/faces). Difference between Left to Right and Right to Left.

- If you picked VDM, it may be even used in any tool that does not support VDM (like paint room tools). In this case it will be used as anti-aliased projection from the top. It simplifies alphas creation a lot. Just pick any detail from the "dirty" surface and use whenever need.

- The Pick & Paste tool for the VDM-s picking improved - much more predictable and stable VDM-s picking even over complex and not clean shapes.

- Fixed problem when autopo symmetry auto-detection may be randomly failed.

- Better visibility of measure tool lines/text.

- Fixed set of problems related to moulding, small-scaled objects support, complex shapes with multiple vertical slopes allowed as well.

- MOULDING moved from Undercuts to the separate tool.

- Usual gizmo improves, less cluttered with plane scaling planes, better looking (anti-aliased).

- Mush better "Smooth selection" in pose tool, works better for irregular triangulation.

- To Global space, To Uniform space keep symmetry settings.

- Fixed several problems related to shaders - (1) sharing the shader with custom textures works correctly (via 3dcpack), (2) Replacement of the normalmap for the shader (if you edit it as permanent shader) works correctly.

- The Measure tool little improvement: in case "Measure is relative" the values show in units, not percents, any measurement line may be assigned as unit (the "Set as unit" button in eash line settings). Show subdivision displays the ticks proportional to units.

- Influence area is stored correctly within presets and tool settings.

- Fixed "File dialogs from tools do not close under macOS"

- Fixed problem when bas-relief may result in strange non-uniform object.

- Measure tool got the option "Measurement relative to the unit" to be able to measure proportions, for example proportions of face or body in percents relative to some unit.

- All surface brushes based on BrushEngine got new parameter - the influence area customization. It is important to limit the brush influence in tight areas.

- Fixed problem of cutting folders names in different items lists like shaders, alphas...

- Bright previews for VDM alphas

- Major improvement of the molding tool. I developed a new sort of Boolean operations that are always stable, lightning-fast, and applied it to this tool first. Now you can create molds for meshes up to 70-100M, which is unreachable in the industry. The result is subdivided adaptively, so the mesh at output will be relatively not too heavy. It is much, much faster; on my PC, molding the 50M mesh takes 6 minutes. The principle of fast Booleans may soon be used for other important tasks - real-time Booleans, even for heavy meshes. Developing of that algorithms took some time, but the result will influence on the whole 3DCoat, not just on molding. This improvement may really be game changing, because industrial molds of very detailed objects may be done via mesh in 3DCoat when using NURBS is just impossible.

- Fixed problem: when you open old sculpt scene the shader may become gray instead of usual look.

- Tool "Slide edges": bug fixed for Slide ring loop

- Saving rotation modes - rotation around the vertical axis or free rotation

- Little Improvements in the new Room "Mesh to NURBS"

- The reference color (Sculpt tree->Reference color) functionality restored.

- Fixed critical instability in render room.

- The retopo/modeling shell acts within the selected faces groups/uv-sets to avoid removing the whole connective area.

- Fixed the painting artifacts in per-pixel painting [at least, after fix we can't reproduce it]. They was appearing sometimes after DEL or Undo.

- Better symmetry detection for ABF unwrapping. Now if island is symmetrical, the unwrap should be symmetrical.

- Workaround for "2023.23 crashes upon start on macOS"

- Shader for primitives changed, now primitives rendering is much nicer.

- Voxel extrude supports "Ignore back faces" correctly, now it may be used over thin surfaces. Surface-like checkbox allows using alphas with mixed positive-negative extrusion correctly.

- Fixed all crashes found in automated bugreports you sent to us. Corrected problematic import of surface/voxel models from start menu (huge ones was crashing scene in some cases).

- Rendering of splines in retopo/stroke improved, also fixed several problems related to that tool.

- "Generate molding curves" asks for the curve points density. The quality of the generated curve drastically improved.

- In the molding toolset, the top and bottom shapes have adaptive subdivision, with polygons being dense near the parting line and rarer beyond. Thus, the polycount of the final shape is essentially reduced.

- Curves with regular points (without user-defined tangents or B-spline points) got much better and predictable shape. There was problem when distance between spline points varies too much. In this case the was loos or zig-zags near point between long and short chunks. Now it works more intuitively, allowing operating over curves with free points much more accurately.

- Fixed the issue of unclosed curve in retopo stroke tool if the lasso, circle or ellipse used.

- If you activate the toolset command by hotkey (or via the script, or via the space panel) the command button will be centered in the left panel.

- Voxel color works correctly when you save/load the scene partially using RMB->Save Volume/Import 3B file.

- Almost all drawing modes (except regular draw mode) support shape multiplication. If you paint any shape (rectangle, lasso, shape, stroke) and press numerical combination, the shape will be multiplied, so you may draw multiple shapes at once.

- The new important drawing mode introduced (within the E panel) - the Shapes. You may add any EPS file there (or drag curve from the curves tree) and then draw with that shape. Non-closed curves allowed as well. This new mode works transparently for all tools similar to lasso with the predefined shape. The 'R' to round, 'Alt' to rotate, 'Space' to move, 'Q'(or other modifier) to make uniform supported. In case of non-closed curves the border width used to set the line width.

- Fixed possible (in some cases) crash when you change the current language.

- Fixed mesh destruction when you use topology-changing tools (like snake) and then add multiresolution levels.

- Fixed problems related to co-existance of Python API and Core API, some Core API projects stopped to work because of Python API, now it is fixed.

- There is new option how 3D Coat gets form vertex - > edges selection: with expansion or without that.

- Some python samples (mesh+primitives) was closing 3DCoat, fixed it.

- The custom items inserted by script into the menu/toolset may be removed by RMB->Remove...

- Fixed problem when: you add mesh to palette it does not appear in list until restart.

- Corrected the problem: if tools switching lags, the activation tools by hotkeys may become buggy.

- Python API fine-tune, extended a lot the Mesh class, non-trivial examples of usage (breaking the object)

- Python API updated, polished, better doc, more examples, especially important is GeneratorExample.py, it contains example of the simplest non-destructive generator.

- Multiple small bugfixes

- Voxel object->RMB->Axial symmetry corrected

- The Core API restored, now it works correctly (it was broken for 2023 builds).

- The Python scripting support in 3DCoat preliminary release. It is still in development and testing sand growing stage, but the base version already available, including basic documentation. We will add more functionality, samples, improve functionality in next builds. The Python API is very close to Core API, same classes, same functions, same logic, but applicable to the Python. Currently embedded Python 3.8 used (as last that supports Windows 7). No any additional install needed, all included.

- 3DCoat > Edit > Preferences > General > Store Window State

- Fixed problem of text correction (text not applied locally).

- Fixed several problems of voxel extrude tool.

- Fixed stamp + voxel brush engine with color.

- Fixed narrow, but important problem of hotkeys: if you assign hotkey to the tool that currently present in UI, then switch (say to voxels) and try to activate that action it will now be triggered anyway if it is generally applicable.

- The new mechanism to extend 3DCoat implemented - some (more heavy) assets like VDM alphas may be downloaded right from the alphas panel (if you will get to VDM folder). Generally this mechanism will be extended to other assets as well.

- I reviewed all automated bug reports and fixed almost all of them. Every bug report is valuable and helps to make 3DCoat more stable.

- The Pick & Paste Surface Sculpt Tool, located near the Extrude, allows you to grab a feature from a raw surface, create a Vector Displacement Map (VDM), and use it with Extrude to duplicate the feature. It doesn't require a flat or nice surface to grab the element; it automatically unwraps and flattens the edge. You can also export VDMs as EXR files to use in other applications. Additionally, you can add external VDM alphas (3 channels, 32-bit, EXR/TIFF) into the Alphas panel and use them in the Surface Extrude.

- Fixed flipped alpha preview in activity bar.

- Fixed a small UI bug - clicking on activity items with the right mouse button triggers the properties, but they close if you move outside the activity area.

- Bigger resolution of alphas preview (if you add new alphas).

- Preliminary (early stage) support of VDM alphas in Surface/Extruder tool. 3-channels, 32 bit EXR-s are treated as VDM-s. Later it will be extended (picking VDM-s from any raw surface, color, making VDM from any model, support VDM-s in voxels and in all brushes). All this is in gradual development, exposing just this small piece.

- Fixed the problem of installing a license via clipboard text.

- Fixed problems related to curves editor window: resolved contradiction between properties rmb, curve point mode rmb click and rmb & drag to change pen radius.

- Fixed major problem of the 10th build: the workfolder was moved to user/3DCoat if the Documents folder was within the OneDrive folder. If you used 3DCoat in that configuration, 3DCoat will detect it and offer to move files to usual location - Documents/3DCoat.

- The licensing method has been updated to simplify the entire process. To install the license, follow these steps: Click "Login" in 3DCoat without entering any information, then the website will open. Log in there, and you're done. Of course old methods (via license file) work as well.

- Fixed a lot of problems related to the activity bar. Now it is much more convenient. In details: (1) switching folders refreshes content immediately, (2) Correct icon in Alphas tab, (3) Correct show/hide of the items panel, there was problem that panel hides unexpectedly if the right panel width is a bit bigger than default.

- Retopo/Modeling Room: The intersection tool of the low-poly mesh now crosses all visible mesh.

- Finally solved all issues to conversion normal-map->displacement in smart material editor. The normal-map format detected automatically, displacement orientation corresponds to the color map.

- If the "Surface-like mode" enabled in Voxel Brush Engine - based brush, negative values in alphas supported as well. Just as example, the brush "Voxel Skin" introduced.

- The important changes for ALPHAS: now alphas imported from images (including exr) may be mixed positive and negative, it allows making more realistic skin details. Negative alphas work for draw/extrude-like brushes in sculpt room. Additional option - Alphas may be imported as rounds with accurate falloff, it simplifies making alphas from the raw textures a lot. This option available in alphas palette or using drag&drop.

- Principally solved color picker problem.

- The huge file removed from installer that was responsible for automated bugreports. I found way to send informative bugreports (as before) but without that database. It also leads to the better protection of 3dcoat from illegal hacking and reverse engineering.
