I have this problem that when I paint an extremity on a character and other body parts happen to line up behind it, the brush paints right past the space between the faces.
Now I know, a simple face mask would solve the problem of painting unwanted areas, but the problem is that Blender also needs a lot of resources to calculate the distance between the faces, which takes multiple seconds, between every brush stroke. and it does that BEFORE it checks whether the faces are even selected for painting! The further away a face, the longer it takes. I don’t know why this is happening though, as I never dealt
with that problem before… It makes the job unbearably tedious.
Is there a way to tell Blender that I only want to paint what is in close 3D-proximity to where the cursor is clicking? Just like in weightpainting, where spherical and projected falloff can either affect everything that’s in line of sight of the brush, or just what’s close.
