I have main mesh and I also have another mesh that is painted and I need to transfer these colors to the main mesh for my work.
I did UV for my mesh. I also added a color attribute to the painted mesh. And for the main mesh, I connected the node of my UV.
I also present you my baking settings.
After all this baking, I get this result(Eyes are a different mesh):
I wanted to upload the blender file, but I couldn't reduce its size to 30 mb, so if you need it, here's a link to the Google drive:
UPD: My search has been going on for 7 days now, so I decided to add some more information.
My system: CPU: Ryzen 5 5600H | Video card: Gtx 1650 4 gb (studio drivers 536.99) | 16 gigabytes of RAM | 500 gb SSD M2
I used different drivers for the video card. I also watched a lot of baking videos to learn about possible errors. I looked at a lot of forums. I also fixed overlapping. I wanted to check if it was a computer problem. But I don't have any other computers or friends with computer to check.
Also, I noticed that if I don't clean up the image, I can see that the transparency is placed in the shape of my UV.(so I could assume that the problem is with taking the colors from the original model, but I'm not sure)
I decided to record a video of my actions. Because I can't find the answer and don't know why the baking doesn't work. Maybe I'm making some mistake and don't realize it. So if it helps, the video is available here: https://youtu.be/GZMNrrCo6lk?si=Pt9XA0l9ByhzNUAh
