I am trying to texture paint onto a mesh with a lot of sharp edges and tips. These areas do not seem to register with the painting, which creates artifacts. I have tried using different UV unwrapping methods and pretty much ever brush settings I can think of, but it doesn't help. Why does this happen, and how do I fix it?
After playing with the UV maps more, I have found that the problem went away if I didn't allow Seams/UV edges in those areas. I had thought I had ruled this out, but I had used too low of an angle on my Smart UV unwrap, and so had still ended up with an edge in those areas even though it wasn't marked as a seam.
