UV mapp from maya ended up useless!
 

I just exported my Zbrush file to Maya and the polygons were separated for some reason. The main problem was, I had already UV mapped everything in Maya into the UV space and did some detailing work on it in Zbrush. When I exported it back to Zbrush, all my UV maps were gone!!! Instead of the layout I had in the UV space, I had a bunch of 2x2 blocks of UV's going across the UV texture editor! Why did it do that??


Problem number 2 was while modeling in Zbrush, my polygon was no longer uniformal. I clicked on frame and some parts were separated in colors and I also had triangles around the deltoid areas. I will screen cap. Please help me! This is the second time exporting something has screwed me up. I've never had any success doing it yet. Thanks!
