I was using a proxy recently and noticed no issues. Can you test on a sample object from the splash screen, to try and narrow it down to either the current mesh having some kind of corruption issue or if this is a recurring problem no matter what object is used?

2. Change the radius of a curve point. Left-click and drag: hover your cursor over the specific curve point, change the Radius. Left-click and drag to change the radius of that individual point. The radius value will be reflected by the current brush size/pen radius setting.   3. yes, the interpolation only is active on curved tangent of points

QQ20251218-22446.mp4 1.When performing boolean operations on two curves, you always have to switch the "view base" option to see the results in real-time. QQ20251218-225151.mp4   2.I understand that the thickness of the result from the "run brush along projection" option is determined by the brush size, but what determines the thickness of the result from the "brush along curve" option? I've tried adjusting the brush size but it doesn't seem to have any effect.     3.When dealing with curves that have sharp angles, the "run brush along projection" and "brush along curve" commands consistently fail to adhere to the path.

Is this solved? I am having same problem with latest version, 2025.15  Never mind, figured out.

If he can't get to it soon (their situation over there is not easy as we know) we could make a guide to make our own Flatpaks, just until they can properly release them to the wild. For the adventurous, the ones in need (nothing works here anymore, for instance) and for the curious. It could take a while for Pilgway to get to it, as we painfully see. It could serve as a proof of concept and test bench. I would gladly help writing the guide if you'd like to. Don't hesitate to contact me if you feel I could help.

Erik Martinez Sanchez shared this info:  I also emailed with Affinity about why the PSD was not reloaded with external changes made in 3dcoat, and it appears to be a limitation of theirs:    

Hi Go to the menu Edit > Preferences. Navigate to the Viewport tab (or search for "Vertical synchronization"). Check the box for "Vertical synchronization" to enable VSync.  This is beneficial for reducing the load on your GPU when working with high-polygon scenes

I'm running v 2025.15 on Windows 11.  I have an RTX 4070ti super and 128 gigs of ram. In the sculpt room I have a proxy mesh enabled.  Every single brush stroke I make causes 3D-Coat to max out 1 core of my CPU for 3-7 seconds and then it returns to normal.  During those 3-7 seconds I can't do anything.  I also notice if I navigate to another window - for example right now I'm typing this message - and I go back to 3D Coat and try to simply navigate the viewport, the CPU shoots up to 100% for several seconds and then it lets me navigate the viewport. This isn't a crazy big model, so I'm not sure what's gong on. Any ideas? Thanks, Paul  

Yeah, I built flatpak of 3DCoat and sent to Sergii. Did not get any feedback from him yet, I  hope they will continue with flatpak version, not much work to do build it, plus you cover every linux distro with it and no more headache with dependencies.

Did you follow these steps, in the video? If you did and still don't see the applink addon in Blender 5.0, try adding 3DCoat & Blender to your EXCEPTIONS list in your Firewall and Anti-Virus. You may also want to check the User Account Control settings in Windows, because it would seem to be some kind of PERMISSIONS issue. Someone in the comments section complained that the Applink doesn't work because they haven't installed Blender, but are using a Blender Zip file to launch Blender and if that is the case with you also, I would try to install Blender. I am pretty sure 3DCoat cannot access Blender files through a Zip file, but perhaps a Pilgway developer can chime in about that.    

https://www.cloudcompare.org/ CloudCompare is a 3D point cloud (and triangular mesh) processing software. It has been originally designed to perform comparison between two dense 3D points clouds (such as the ones acquired with a laser scanner) or between a point cloud and a triangular mesh. It relies on a specific octree structure dedicated to this task.  Afterwards, it has been extended to a more generic point cloud processing software, including many advanced algorithms (registration, resampling, color/normal/scalar fields handling, statistics computation, sensor management, interactive or automatic segmentation, display enhancement, etc.).
