   "seam" apears on object along uv map when normal mapping
  I'm Using Rendermonkey to make normal map shaders with melody.These are my Melody settings.http://i4.photobucket.com/albums/y137/Reuomi/Melody.jpgAnd heres the problem. Look at the seam, how do i remove it?seam apears weather i use object space normal map or tangent space one.http://i4.photobucket.com/albums/y137/Reuomi/rendermonkey.jpgTaken from Maya:http://i4.photobucket.com/albums/y137/Reuomi/uv.jpg   
  how was your normal map created and how are your NBT created. We also had a lot of problems with this, but in the end it's jsut finding the correct matching methods. I am using the ATI way to calculate my NBT and then most of the time my normals don't have seams. In ZBrush you can even specify the way how your normal maps are created ..And this is mostly an artistic problem. I think you can find quite some information about this in the forums of CG SocietyRegards,Kenzo
