Hey all, Does anyone know if it is possible and how to reverse the vertex normals on a vertex shader level in ShaderFX for Maya? What I'm after is equivalent to disabling the "double sided" and enabling "opposite" on the shape node of a polygon object. But I can't find anything regarding vertex normals in the Vertex Shader…
hmmm. not sure. Currently this is handled in the pixel shader where we have the culling information to know if a face is facing front or back. Don't think we have that info available in the vertex shader.
