Hello all! I'm a new user to UDK, so I'll prefix this with it's probably something silly on my end and get right down to the problem.
I'm trying to import some models and maps I made in Maya/ZBrush that seem to display just fine in Maya's Viewport 2.0 and in renders. However, when I import the model (a skull in this case) into the UDK it gets this weird seaming problem on the side and back. I've narrowed it down to something in the normal maps, but these were created in ZBrush which should prevent most seaming issues. Any ideas on what this could be?
Here's the object in Maya's Viewport 2.0 without any visible seam problems.
Here's the material editor view of the object in the UDK with the normal map issues visible in the material preview and the mesh preview (in red).
