tangent space generation

[bobjob]

I have got my obj loader working fine with tangents and binormals. Currently the loader generates smooth faces. The only problems is along seams.

I was wondering if anyone else has had this problem, and what are the ways of fixing it.

I was considering generating extra triangles from joining faces and giving them new texture co-ordinates so they continue accross the seam. then removing the extra triangles at the end.

Iv had this problem for a while and havnt really seen any good solutions
