I have this issue with 3DCoat where it suddenly started giving me errors 'unable to write to the folder', 'unable to rename the file from json1.txt' and 'writing to data folder is impossible due to lack of permissions!' on program startup and 'there is not enough disk space to write the file'. My settings are in C:\Users\%MyName%\Documents\3DCoat2026 Things I've already tried: Running 3DCoat as administrator - doesn't help. Deleting 3DCoat and 3DCoat2026 from documents folder - doesn't help, the program starts broken with no text anywhere Reinstalling 3DCoat - doesn't help I can't relocate settings to another folder because I can't close the 'File write error!' window and it prevents me from selecting anything.

Sorry I don't have access to v2023 anymore, but on 2926 is working as expected

Hi, When painting with the brush and a brush stroke, I can erase by holding CTRL pressed (I think it inverts the tool) When painting with brush and any of the lasso type strokes, that doesn't seem to work. Should this work? Only color is active. Currently, I have to switch to the eraser tool to do my erasing.   v 2023.37

Still no rounded edge/bevel shader like in Marmoset toolbag? I think Blender and Houdini has this too.

Hi, When I have multiple objects  to paint in 3dCoat Textura (latest version 2026.24, parts of the uv texture appear on that of another object. To illustrate I am attaching a screenshot example. There are 3 different objects, cylinder, cube, and cone, each with UV maps with different names. As you can see, on the cube, parts of the cylinder map appear.

I think it will be renamed because there is already a competing application called CAD2Poly. My suggestion would be something like CAD-QuadGen or CAD-Quadrific. Any other suggestions?

coat 2026.24 Hi! Thank You for the new update. When i import Roughness or Metallic in PPP , the object material is not updated until I paint something on the corresponding Layer, then I have to paint Poly by poly to update roughness/metallic. This is without any materials applied. (like painting before gpuppp version). When Reloading its the same, so i can just post the Cube 3B. (just paint on roughness or metallic layer) All the Best, and keep it up! test.3b

Convert CAD models into quad meshes with CAD2Quads. This demo shows mesh density control, rounded surfaces, multiple bodies, and topology around holes, followed by mesh inspection in 3DCoat.

Hi, I am using the latest version of 3DCoat Textura. I moved some windows panels around, such as having the color palette and brushes window open. I saved the workspace and also checked "store window state" in preferences. However, when I close and reopen the program, my saved windows workspace only appears for a second. The window then flickers and it resorts to the default setting. myworkspace.3dcpack

No separate version — one download, and it does not need OneDrive. That list is only the fallback order: the Documents folder Windows itself reports first, then %USERPROFILE%\Documents, and the OneDrive paths last. On a machine without OneDrive it stops at the first entry that actually holds 3D-Coat's data folder (a 3DCoat folder with UserPrefs inside). And inside 3D-Coat nothing is guessed at all — the extension asks 3D-Coat itself which data folder it uses. So if it works, nothing to do. If it doesn't, run Scripts > CoatMenu > Diagnostics and paste the extension and data lines here; those two say everything.
