Nalim Posted March 14, 2012 Posted March 14, 2012 I'm using Zbrush and 3d studio for my mods mainly, My UV mapping I do in blender. As I use zbrush for making normal maps/displacement maps I really need my meshes in one piece but the UV maps are cutting them. I'm certain this happens in one of the many exports or imports but I dont know which one. Is it when I export to .nif from 3d studio?

[/quote'] Like you said, you do the UV mapping in blender, this means that in blender you're cutting your mesh.
Caliente Posted March 15, 2012 Posted March 15, 2012 the .nif file format duplicates vertices at UV seams -- .obj files keep a separate index list for UVs that avoids that, but .nif files have no such luxury (each vertex has exactly one uv coordinate). Thus, a vertex with more than one UV coordinate is duplicated. To avoid seam splitting, I've found it works to use Blender's Remove Doubles command. When you re export the mesh, they'll double back up again, but it the order is preserved in my experience.
