The texturing and lighting forum hasn’t been any help. Thought I’d try here instead. Every texture I bake in my current project has started looking like this:
I don’t know why, or what I did to cause it. It wasn’t happening to begin with, and I can’t remember changing anything notable to make it happen. It just stopped working properly.
These lines are exact diagonals across faces, from one corner vert to the opposite. It’s like pixels just not getting filled in upon rendering.
My blend file is here, to help with diagnosing and testing the problem:
The cause of the problem is something to do with ambient occlusion. If I disable it completely, it doesn’t happen. However, AO is essential, so that’s not a good solution. Setting AO mode to approximate makes the lines fainter, but does not remove them.
Also, something odd I’ve noticed, if I create new objects in the scene, they don’t suffer this issue, even with the same material.
Can anyone tell me what’s wrong, what I might have done to cause this, and how to fix, or work around it?
