How to get vertex normal in surface shader
Is it possible to get access to the world-space vertex normal, in a surface shader that also uses a normal map?
Writing Surface Shaders lists a worldNormal
member, but it sounds like this is the normal from the normal map, transformed into world space, rather than the original vertex normal.
