If you adjust the UV's yes it will screw with the displacement (as the UV's are whats determining the position of the map). In Zbrush you can swap a models UV's not too sure about in Mudbox though. Thanks for the help, in mudbox I went to level 4 I believe, it's like 600,000 faces or something close to it if I'm remembering correctly. For the crashing issue, not too sure but have you tried using the dispalcement map as a mental ray native .map format as it tends to run a lot better when using one of them. I heard about the .map but no idea how to change it to that. Right now they displacement map is a .exr file I read thats why I was having my first issue, but then this other one happened with the .exr file. I'll look into .map format and how to go about doing that. Thanks again for the help, I appreciate it.
