I have a little experience with SHADE/Renderman & none with 3D Studio. I have two questions: Are either of these products sensitive to the "orientation" of surface normals? In other words, give a surface defined in 3D space, do either of these packages "care" if the surface normal is pointing "toward or away" from me? If "yes", could I assume that a routine that "aligns" and/or "reverses" surface normals for a mesh would be useful? Ang
