Displacement issues
-
I tend to have this issue pretty frequently, and it is quite bothersome when using some textures.
Basically I have a ceiling grid texture and displacement map that I made. The displacement map is just the grid, no aliasing on the lines or anything.
However, when I render it. I get weird wavy or squiggly artifacts. This happens to me with a lot of my brick & tile textures, too.
What setting do I need to adjust?
See image for example.

You can try to Set the Filter value in the displacement map to 0 to see if that helps.

I think I fixed it... I turned the subdivs down to 1. Weird.

2.0 bump mapping has improved significantly. I would not use displacement on tiles or bricks. Seems like an incredible waste of render time to me. Try bump, trust me.
