Well, the refraction would be at the material/object level, as part of the
interior. Water is IOR ~1.3, glass, jade, and pearl are ~1.5, and diamond is
~2.4, not sure what ivory would be.

Anyway, these are just textures that I defined as base SSLT-only textures.
I've noticed that the current SSLT implementation doesn't play well with complex
pigments like color_maps or image_maps; it just seems to ignore them. So I've
been experimenting with layered and patterned textures instead of just pure
SSLT, getting results like these (with spec, roughness, etc in non-SSLT
layers/patterns).
