I can confirm in Arch it crashes on using the file dialog. To test it, I installed a fresh Endeavour OS (basically Arch with some script helpers and saner installer) with Cinnamon desktop (to rule out Gnome and GTK4 issues) on a spare SSD and yes, it launched fine, but on using the Save as... menu it crashes immediately. I could install any other distro/desktop if needed, but I think this is getting us nowhere. With the available knowledge, time and other resources available, the sooner SERGYI manages to make a Flatpak the better, really. Put everything needed inside, and be done with it.

Magic! But this is not that 'dotted' hiding mode. That dotted hiding mode works based on the normal of the polygon. When I toggle 'ignore back faces,' it seems that 3Dcoat doesn't see that object.

Figured that too. I really did not get anything for latest upgrade I paid. None of the versions worked on PopOS (Ubuntu 22.04), from Feb 2024. So I am not really holding my breath here. I also think that this will continue like this as you are just human and I do not see how can you keep doing this in a future. Will keep version from Feb 2024 and slowly start switching to Blender and MARI. Both work flawless on Linux. Anyway thank you for your hard work Sergyi! 

I can't. Запись экрана 2025-01-28 131752.mp4    

WHY oh why, I can paint on hided mesh [or voxels]? win11

I can't repeat this either. The name of the retopo layer will be rewritten. But the faces will not be deleted and will merge with the new ones.

https://www.artstation.com/artwork/nJDxo1 Antoine Zavagno demonstrated how he created an eye-catching 3D take on Kenpachi Zaraki from Bleach that looks fully 2D, sculpted in ZBrush, textured in 3DCoat, and rendered in Blender.

After baking to Paint room,  UVsets becomes Surface Materials, Polygroups are converted to Paint Objects. Did you added seams and baked the models ? It is hard to tell without an UV preview screenshot (Windows > Panels > UV preview) This video demonstrates the usage of multiple UV sets in 3D Coat, and briefly touches on the new UV tile support. If you export with one UVset and 3 polygroups created you will get one .obj file containing 3 objects. Those 3 objects will have their own UV Maps, but the UVs will be distributed like they are in 3D Coat (i.e. they won't take up all of the UV Space, because they won't take up the room that the UVs from the other objects were occupying). If you want a separate UV Map for each object that takes up all the UV Space, you would need to create 3 separate UV Sets. Then move the geometry for each into those UV Sets, and Unwrap again. Then export. You create new UV Sets by clicking "Add New UV Set" from the top left menu. You then move geometry to that UV Set by first selecting it, then changing UV Set, then clicking the drop down menu to the right of that ("Move Selected") and then selecting your new UV Set. I hope that helps. 

I am real noob at UVs, a UV set is a whole 2k/4k/8k texture ? or what is a uv set exactly. I just baked it and checked the uv sets next to simple checker on the upper left, for each layer of the poly group, 3dcoat makes a uv set correct?, but all these uvs are fit into only one image 2k/4k/8k texture correct? I mean, when i bake it seems 3dcoat will create 3 textures images of 4K, but later there will be only one texture when i start texturing... please help me understand how this works

Right to Simple checker on the upper left display yo can see the UVsets created

I am baking and when i UNCHECK treat material as separate textures i still have multiple uv sets, is like unchecking that option or checking it doesn't change nothing, is it a bug. Or after i hit OK there will be only one UV set? Where can check how many UV sets are, after clicking OK asd

@SERGYI I have read your messages, they make me feel sympathetic and a little sad. Studying the history of Pigway and having conversations with some of the developers, I am beginning to understand your burden and the burden of the team as a whole. In my subjective opinion, one of the reasons is Mr. Andrew himself as the head of the company, who took on too much for himself and the team. Too many ideas, too many ambitions, the desire to become the new Blender, creates a big burden that a small team can hardly lift (as far as I know, you are about 5 programmers). About Linux, okay, I get it. Actually, in my video I tested the last two builds, as you wrote 32-1 and 27-1. I follow the forum and try to follow your instructions. I think it will not be always easy for me to recognize which problems in 3DCoat are Linux only and which are common, but I will try. “3DCoat project is essentially a Windows-only project” - yeah i felt that. I learned this after I bought it. You just get enough sleep , I'll wait

mines working fine 2024.32

Same here on my Arch install  I could be way off but I think the culprit on arch is the linking directly to the library instead of the symbolic link

Hi, i did a "retopo via decimation all visible parts" of this manequin, then on retopo room everything is invisble... why? and 2nd question i was curious, if i RE decimate again all layers in sculpt room, will the new decimation overwrite the retopo layers with same name? or will it make new ones?  Thanks

The biggest problem for today with Linux build is GKT3 functions gtk_clipboard_wait_for_text, gtk_clipboard_wait_is_image_available, and gtk_clipboard_wait_for_image. I found a workaround for the crash after calling them on my Ubuntu 20.04. But the modal startup dialog with the license dialog is still flickering on my machine. When I remove those functions, there is no flickering. I suspect those functions are why you see the viewport disappearing on your machines. I plan to see how those functions work in GTK3 under 22.04 this week. It may reveal something important about this matter.
