I'm trying to copy the color from the same high poly mesh which have different Uvmap.
After that I copied the same mesh and made a new material and texture for baking (On the image below I displayed original texture but I actually connect the node of the copied mesh to new empty texture). This time I used smart UV unwrap. I used cycles for baking and set the bake type to diffuse and enabled only color(You could see on the inspector section).
This is the result after baking. It has a lot of noise and quality doesn't look good. I set the render value to 1024 and enabled denoise option. What could be the problem here? High poly or different UVmap? How about selected to active option on baking that I used to copy the texture?
