please could someone help me? I've after long time of peace again encountered a very persistent tangent problem. I hate XSI... or my modelling skills. Or both.
Problem is as follows: the tangent map looks fine in XSI. The vertex normals are angle-weighted vertex normals generated with MeshLabs. Also they are normalised. Mesh uses its own set of UVs, based on a cubic projection and then refined.
In Sins the model is lighted 90 degrees off - if the light comes from the side, the model is lighted from behind. Also the selfshadowing is completely off
I'm grateful for any help or advise.
