UV problems

Will J 215 posts13 Mar 2008Hey folks,
Well the apache's texture work is looking good so far, however I'm having a problem. There's a problem with the UV's of any parts of a mesh that I joined from two symmetrical meshes (usually after mirroring and merging the verts.) Though it is a single shell, the UV's on the ducplicate side are inverted (if I want to project from +Y they are projected from -Y for example.) I've looked for a function that would solve this in the UV tex editot, but no luck so far. Any thoughts? Its pretty annoying as the bumps come out inside out on one side of the meshes, and where the UV's are sewn it looks terrible as you can imagine. Thanks in advance

Will J 215 posts14 Mar 2008A picture might help you, but there's not alot to see wrong because the color channels look fine, just the bump map is inside out on one side of the body. I'll try reversing the normals of the incorrect side, that might work.

Will J 215 posts16 Mar 2008Well, I couldn't figure it out myself, but I know what the cause was. Instead of using Mesh > Mirror geometry (which would have probably worked) I used the simple duplication and minus value in one of the horizontal axes. Welding the two sides of the mesh (one with a minus X value) probably did something to the UV's of that side. Oh ell, I've learnedmy lesson.
I have a workaround though, I just inverted the colors of the bump on the bad side and now it looks fine.
