Surface (mode) Booleans are less reliable than Voxel mode Booleans because of self-intersection issues and such. Try to switch your Sculpt Tree layer to Voxel Mode first. If you need to switch it Surface mode thereafter, you can.
Is it possible to link/reference resources in 3DCoat without duplicating them? I'll try to explain what I mean.
In software like Blender and ZBrush, you're able to use brush alphas and other resources without duplicating the files in your system's directory. For example, in ZBrush, I can open the Lightbox, go to Alpha, navigate to any folder I want, pick an alpha, and use it. The location doesn't matter, and the file remains exactly where it was in my directory. The same can be seen in Blender: in Sculpt Mode, I can add a Texture to my brush, open the File View, select my alpha, and use it on my brush without another file being created on my computer.
In 3DCoat, I know that in the Brushes, Stencils, and Strips panels, have the option to "Add Existing Folder" in each panel. However, I've found that this duplicates all of the files in the original folder, with new copies in 3DCoat's UserPrefs directory. I don't like this because it means that to work with my existing alphas and other resources, I need to store a copy for every other piece of software, and then store a second copy for 3DCoat only. With high resolution, uncompressed images, this can lead to gigabytes of wasted space.
Is there a way for 3DCoat to use my original alphas and other resources without duplicating the files into UserPrefs?
Is there a way to disable boolean when using tools that append new meshes like spline / import? Fairly simple test cases fail to boolean when using repeated shapes
Tried version 2025.16 and the problem with folders is still there - can't rename created folder, it's still named 0. New folders correctly, though, so I'll move alphas to the new folder, I guess.
Oh, it was mentioned in another thread, but I'll bring it here - Don't use sticky keys option in Preferences doesn't work, 3DC is using Sticky keys anyway.
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

1.When performing boolean operations on two curves, you always have to switch the "view base" option to see the results in real-time.

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.
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.

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
