I've tried everything I can find and think of to make UV Unfold work correctly. Here is what I know so far.

 

I tried flipping the texture map on an object file exported from Hexagon 2 with UV Unfold UVs. It then showed up on the object file but the texture was very distorted (showing the objects white) at every rotation. Then I saved the same file as a Carrara file and the texture map came in fine but when I tried to use the Hexagon exported displacement map on the object it looked bad and the displacement did not work as it should at all.

To sum it up, it appears that Hexagon 2 exports displacement maps in object files just fine, however if UV Unfold is used for the texture map on the object file the texture is messed up (no matter what). On the other hand the UV Unfold textures come in fine on an object exported from Hexagon 2 as a Carrara file but the Hexagon 2 exported displacement map does not work on the Carrara object.
