You may want to test 3DCoat Linux builds in a not outdated distribution (or old version of a distribution), and see that it doesn't work, really, to have a base reference. See the what, the how and the why, possibly, to 3DCoat not working in a modern Linux. Then, you can try the Distrobox route. I haven't written a proper guide yet, was waiting for some things to improve first; anyway, there are step-by-step instructions around these forums, in the Linux section. Basically, one has to install distrobox, then an Ubuntu 20.04 (oh, dear!) image with Nvidia support to have hardware acceleration if one uses nVidia (--nvidia flag now works, it didn't for a few months), and then run 3dcoat from the distrobox image. It works, mostly. There are ways to make launchers to bypass entering a terminal and then entering the distrobox image and then launching 3dcoat but that's for another day. In my case, scaling doesn't really work well, so tiny interface in a 4k monitor; and I forgot if the Wacom did actually work (I assume it didn't, but maybe now it's better). Since there were a few more things not ready yet, I confess to have given up, waiting for more mature, newer versions of 3DCoat. That being said, and as annoying it is that releases take months, then a few quickly in a row, then crickets again for weeks... SERGYI did make several substantial changes that are not precisely minor to make 3DCoat work well in Linux going forward. It's clearly improving, although with serious hiccups here and there. The move to GTK3 was sadly done so late, that we're now about to ask a port to GTK4 with some urgency before the GTK3 port is really working fine. I think SERGYI will not like that very much, poor soul. We've talked about that in the past. :-) Anyway, if you already knew all of this, sorry for the the intrusion. If not, and need further assistance testing with distrobox (it's really not difficult and it sort of works, yay!) ping me or some of the other Linux users around here. You seem to be determined to try it out. We should help you do just that if you need us. Thanks for your past posts here, by the way. I couldn't agree more with you, as others have also stated. I'm also very pleased by the reaction of the people in charge here. It's good to see how well they take [well presented] criticism and suggestions alike. Good stuff.

Ok, i am following "Linux updates news" i will test your new build and then I'll write to you. I need couple days.

In Windows terms, it's the same as saying on my Windows 8 everything works fine, i don't know what you talking about. We already have Windows 11, Windows 12 coming soon, guys. 20.04 support end in april 2025. I don't want to use old and outdated OS for one soft, while your competitors offer good linux support for modern OS. Your link lead me to 2024.28-02 version (i tested it technically work but not suitable for work), i guess you mean 2024.32-1.

Outstanding comment. Based on such comments, any product should be developed. Regarding tablet support, here is my idea: email me at sergkryzh AT gmail DOT com. I will build some tiny test executables with experimental code on tablet support.

Please try the latest build from here: https://pilgway.com/~sergyi/links-Linux.html In my test, it works as expected under Ubuntu 20.04. Still, there are two noticeable glitches: flickering of the input license dialog and slow/incorrect response of the small buttons on the navigation panel. Regarding tablet support, I don't know what to suggest because my Wacom Intuos 3 works out of the box.

As I said, "3DCoat 202x" crashed after displaying a modal dialog. By excluding parts of the source code, I have found that GTK3 functions gtk_clipboard_wait_for_text, gtk_clipboard_wait_is_image_available, and gtk_clipboard_wait_for_image change OpenGL context in the main thread of the application. They should not do that, and they do not do that in GTK2. After working around this problem, I have built two versions of "3DCoat 202x". The first one is from the old branch for the year 2024: https://pilgway.com/~sergyi/3DCoat-2024/3DCoat-2024.27-01.tar.bz2 The second one is from the new branch for the year 2025: https://pilgway.com/~sergyi/3DCoat-2024/3DCoat-2024.32-1.tar.bz2 https://pilgway.com/~sergyi/links-Linux.html Please compare the two. Some changes have been made since the old branch, 2024. Some tools may be working in the 2024 version but not in 2025. Please report this case directly to my email. Known problems: (1) annoying flickering of the input license dialog with buttons "Login", "Free trial/demo", and "Load license" when moving the mouse; (2) the slow/incorrect response of the small buttons on the navigation panel: Adjust the contrast/intensity of lighting, Move/Zoom the camera, etc. I will fix the known problems (1) and (2). In the meantime, please compare the two builds and notify me about issues in "2024.32" since "2024.27". I can find the code that introduced a problem by reverting to commits.

"3DCoat 202x" for Linux has been rewritten from scratch for this year using GTK3. The code has been refactored, so any future GTK will be easily supported. Here is the latest build for Linux with some known issues under investigation: https://pilgway.com/~sergyi/links-Linux.html

Here is the latest versions for linux. https://pilgway.com/~sergyi/links-Linux.html I don’t know exactly how much time the developers take to release the same update for Windows.  

Hi! In few days, my license will end because i purchased it almost a year ago, and during this year we never seen any linux update at all besides 3DCoat 2024.06 which is broken even on Ubuntu. My question is, does Linux support have come to the end?

changing pose falloff fix it, thanks tho

This worked, i actually i tried that before but it seems i didn't change the curve enough, now i did it again and it made the edge selection sharp enough. Thanks

HMC Voice Command (for 3DCoat) 2025 Update Pt.1View the full article

Reset page to default fixed it, thank you!

this guy gets it ! , i honestly believe 90% of all 3dcoat users are in favour with this , the 3 mains sculpt retopo and paint would be amazing to see worked on ,  unfortunately as he said the other rooms are very basic and far behind and maybe in the future they are fixed but stick to your strengths and ill 100% renew my license! i have done every year for the past 10 years or so , the developers are truly amazing and i trust everything they do , looking forward to the 2025 release!
