Not sure if we can call an RGB approximation of complex IOR physically-accurate, I bet it's going to look quite different compared to full-wavelength.
The Base Color and Edge Tint should also default to Titanium. Maybe we can try on F82 Tint and hope the Artistic Conductor does not look too different.
I think it's better to put this comment above conductor_ior_from_color() and add Equations to map color to complex IOR, from "Artist...
@Sergey if the incoming light is below the surface, we return zero no matter what, so disable bump map trick doesn't have any effect here. See bump_shadowing_term().
I guess there is something…
The darker droplets is because you mix with black based on ambient occlusion, and the pool is occuluded by the droplets <img width="297" alt="image" src="attachments/0ce91947-aa7c-403a-90ad-c51c6…
This is the same issue as bump mapping: when the geometry normal and the shading normal differ, the reflected ray might go below the surface and get discarded. By taking the absolute value of the…
