Displacement problem

#1

Hello. I’m new to Zbrush and I’m getting weird result while exporting displacement map. What can cause that? Thank you.

What do your UV’s look like?

I’ve already solved it. The problem was that when I unwrapped pieces of geometry (sofa) in 3ds max and attached them together I hadn’t repacked uv’s. There was an intersection of them. Thanks for respond!
