Why does my texture have artifacts when I polypaint and then convert my color to a texture map?
The “smoothness” of your color to texture conversion is dependent upon the resolution of your mesh (number of polygons) and the size of the texture (ie. 1024 x 1024, 2048 x 2048…) you are transferring your polypainting to. “Think of each pixel as a polygon. If you want to use a texture with a resolution of 1024×1024 you need at least 1.05 million polygons (1024×1024=1048576) If you want to use a low resolution mesh with a high resolution texture, you’ll need to use Projection Master. Alternatively, you can subdivide your mesh to the insanely high resolution, use polypaint, then save the texture. From there you can bump back down to your lower resolution, delete higher subdivisions, and apply the texture you saved earlier.” – eldee.
