Have same question. My license 3DCoat 2023 Individual will expire in 8 days, but I do not see option to upgrade it. I only see option to upgrade, older, v4 licenses. 

Can some please assist?

Attached is a screen capture of what I see in my cart. Serial numbers have been RED out.

My 3D Coat 2024 license expired Dec 2024. However when I go to extend my license for 2025 as I did last year). I am not given the choice to extend my license for 3DC 2024. I am told that the upgrade from 3DC V4 Pro is already in the cart. Yet when I check my cart it is empty.  However I do have an option to upgrade from 3DCoatV2 to 3DC2024 . How do I purchase a new license for my 3DC 2024? Do I choice upgrade from 3DCoatV2?

The problem is that the Autoretopology operation sometimes does not produce any result at all and does not even create a layer in the Poly Groups list.

Hello! Try to enable this Camera->Rotate Around Object Bounding Box.

Hi   Would you add the option to navigate about the center of the object (Volumetric center) , so, there will be no need to select the pivot point manually every time.

There may be a bug, but just from watching the video you provided, I would use a different approach to this kind of model. It may not seem like a very complex model overall, but it does have a number of complex shapes, which make it harder for the algorithm to do its job. For example, the teeth and eyeballs, if done separately, will have a good result. Then the rest of the body, I would do separately, making a duplicate that reduces the amount of small details (so that the only thing Auto-Retopo needs to focus on is the larger shapes and forms). Once you are finished with the Auto-Retopo generation, you can delete this dumbed down duplicate and use the high resolution original for baking purposes. Also, before running Auto-Retopo, I try to make the duplicate a Voxel object > RMB the Sculpt Tree layer > choose FILL VOIDS. Sometimes your model may have little pockets inside (usually from working with Voxels and resulting from cutting and merge operations). This step will remove those, if any are detected. They can adversely affect the Auto-Retopo result and even cause crashes.

Thank you! I managed to reproduce the bug. Now I will pass this on to the developer.

I run 3dcoat on Fedora kinoite through an Ubuntu 22.04 distrobox image and it works pretty well. I mainly use it for sculpting and texture painting although I haven't tested it for too many hours yet in this set up. I used to just dual boot into windows for 3dcoat and other applications during the wayland-nvidia dark ages. The only problem I've run into is that I can't load .3b files when using the 3dcoat 22.04 executable but it works perfectly fine when using the 20.04 one. I don't know if there's a difference these but I haven't run into any issues yet. 3DCoat-2024.28-02 is currently unusable however. I haven't tried anything to get it to work but the UI just disappears after a few seconds of loading.

ill do a little video soon 

Hi, It's no longer there - all because I opened someone's file that doesn't use 3D Coat - this must surely be a bug? And needs fixing I downloaded from GitHub - change the download name from io-coat3d_main to io-coat3D and now it seems to be, on a primarily test, working again. I did not delete any files or folders whatsoever. Thank you for your help, its appreciated - Hopefully, it's all working again

For Blender 4.3 the correct location is C:\Users\<username>\AppData\Roaming\Blender Foundation\Blender\4.3\extensions\user_default\io_coat3D

Please give more details so that we can repeat this and pass it on to the developer.

Hi, Thanks for the reply - Do you mean under 'Get extensions'? It does not appear there. It's only available, as I see it, under Add-ons

Is right, my Exchange folder is also located on C:\Users\<username>\Documents\AppLinks\3D-Coat\Exchange\ Object texture folder, I let it empty   reinstall the addon on Extension folder, not Addons
