I can take a filled black square and begin painting in it in any blend mode and what you see (weird patterns and shapes appearing inside the painted areas) is what happens. On the left side of the attached image is what appears to be sequential lines of dots with circles around them: these appear 100% of the time if I paint on the UV side of the texture painting workspace, regardless of blend mode, color, brush strength, or any other variable and are not intended. On the right side you can see where the circles on the front of the toes of the character are different shades of grey. Whether I use tones or hues is irrelevant: the color is different depending on where I paint on the model. There are no other maps applied to the model, there is no reason these inconsistencies should appear as far as I can tell. In the video, the color or tone starts solid and turns into a bizarre pattern. This pattern consistently appears, again regardless of color or tone used, blending mode used, or whether it is a new image, filled image, image with completely transparent background, or any combination thereof. I started a completely new file, made a sphere, unwrapped it, created a new texture and began painting on it and the same thing happens.
Like I said, I’m only using Blender’s native tools to create a rough map of where I want things to be, then exporting the UV’s for embellishment in Photoshop. Blending, cloning and blurring seem to work fine, this only happens with the paintbrush tool, so I can work around it. It just would be nice to know what’s going on because I’ve never seen it happen in previous versions.
Maybe I have a corrupted install… I’ll try a clean install and see if that corrects the issue.
