@@minilogoguy18 - I have spent my evening investigating Softimage's support for Tangents and Binormals... if you read all the sub-links in the one link you sent me, then you know it is an "Either" / "Or" deal-- NOT both. Whichever one you apply first is what is written into the vertexes "COLOR" property... the other parameter is expected to be computed by the cross product of the vertex normal and whichever property (tangent or binormal) you applied first. Does that make sense? I verified this with multiple dotXSI 3.5 exports. Also, Crosswalk 2014 does not support XSI Mod Tool 7.5 (...it only supports back to Softimage 2010). @@DT85, @@Psyk0Sith, @@AshuraDX, @@Almightygir - So after chatting with DT I have a question... for normal map baking, is the low-Poly mesh suppose to have no smoothing groups(i.e., a faceted mesh)? And then you could apply the resulting normal map onto a low-Poly version that does have custom-modified explicit vertex normals? Please someone explain...
