This is not correct…
- If you looked at the distance field through the mesh distance field visualizer you would immediately realize this is a problem with the distance field generation.
- If your theory were remotely true, increasing the resolution scale by 10% would not have solved it. But it did.
- This doesn’t even look like the artifact for non-uniform scaling. Excessive non-uniform scaling produces stretching and ringing/rippling in the AO, not black splotches. Here is an example:
I have to admit I’ve never encountered this issue before and I’ve no idea what might be causing it… Sorry.
