Maya ShaderFX, reverse normals at vertex shader level?
polycounter lvl 19
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 Grp prefab group.
Thanks.

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.
So what I'm after is currently not doable in ShaderFX I guess then?
