NathanVFX 0 Posted May 12, 2020 Hi! I've been trying to replicate something similar to Arnold's coat IOR parameter in Mantra. Ideally I'd like to be able to control how much of a coat layer is visible depending on facing angles without affecting the underlying surface, even if this involves breaking the law of conservation of energy. Any ideas on where I could start? Thanks, Nathan Share this post Link to post Share on other sites
NathanVFX 0 Posted May 12, 2020 I've found a way to do it! There's an index of refraction parameter for the coat only if you jump inside the principled core shader inside the principled shader and locate the coat_reflection (PBR Non-Metallic) shader Share this post Link to post Share on other sites
