I am having some problems exporting vector displacement maps. ZBrush doesn’t seem to respect my UV layout.
I’m using a simple 1x1 plane.
At higher subdivisions, there is a cone on the plane.
The UV layout is pretty straightforward. The borders of the plane go all the way to the edge of the 0-1 space.
The problem is that whenever I export the VD maps it doesn’t respect the UV layout. It looks like the information was scaled down to one third the size.
The resulting render in Maya looks like this (plus I’m getting a black edge around the base)
I tried exporting displacement, just as a test. It gave me this weird result…
I don’t know what’s going on! confused(
Any ideas? I wonder whether the fact that I’m using just a single polygon at the lowest subdivision level is causing the problem. My reason for this is that I’m trying to create a tiling Vector Displacement map that can be applied to any surface, so I’d like to work with something completely flat (ie. a plane) at the base level.
Thoughts?
