Hello Carlosan! Could you please update us on this. Is this something planned for fixing in a forseable future? Thanks

Yes.  I have 4 monitors and the 4070ti super only supports 3.  

sorry i havent had much time , i will make a video later on a few things that arent working

Hey! So i have checked all my projects with earlier version (2025.10) and it is working as intended I guess 2025.11 just dont work for me.. Also, forgot to mmention - I am using 3D Coat Textura, not regular one 

Can you tell us in more detail which tools are failing so we can pass this on to the developers?

Yeah, older projects is okay, I just don't understand what happened to this one... 

This crash needs to be fixed. Please share a scene with your object and layers.

To apply an alpha brush along a curve around a curved surface in 3DCoat, you should use the Curves tool in the Paint Room or the Curves editor to define the curve path, then apply your alpha to it, ensuring the curve follows the object's local space.    

I might have had an issue with the Blender version 4.5.3. I downloaded again and it works correctly with the 3dcoat applink.

I've been use this link. It works up to Blender 4.5.3. (Fails in 5.0 alpha. Sends ok but get back fails.) Could be the alpha version. https://github.com/AndrewShpagin/io-coat3d

Where can i find this fixed version ? Dont find it in extensions.blender.org anymore. The "Pointer  to 3dcoat Applink" in link above is also not working here. Sorry, maybe im just too blind to find it. And would it also work with 2024.31 or do i have to be on 3DC 2025 ?  

@paulrus try rolling back to earlier version

have you got a 3060 running along side the 4070ti?

I'm having a bit of trouble with 2025.11 in Windows 11.  I have an RTX 4070ti super and 128 gigs of ram.   I have a PPP model and I want to rebuild the cavity map and the ambient occlusion.  I've tried deleting them, and then recreating - 3DC immediately crashes.  I then have tried to select the layer with the existing map and recreate it, and the same thing happens.  Immediate crash.  Attached is a screen grab for the crash I am seeing.   Any idea on what I can do to fix it?  I'm supposed to be presenting this tomorrow evening, so any help would be appreciated.

I was wondering if there was a setting or something to to make my alpha brush curve around a curved surface?
