I want to create car’s headlight and for this I’ve created simple mesh object from cube and set ray transparency and mirroring. I’ve also set normal map to this object to make my glass grooved.
Transparency, reflection and refraction work perfect, but there is some troubles with object’s shadow. It looks like as from object without normal map. Using displacement instead of normal map solves this problem, but in this case object should have very high subdivison level.
What could be done with this?
