I am trying to render a simple diamond gem with some nice faceted patterns as you would expect.
I suspect there are some content based modeling tricks here (apart from making sure you set up your Ior and subsurface min/max depths…etc . I realize we are not raytracing here but wondering if there are approaches people have used with success. (duplicating the gem, inverting normals, adding additional faceted geometry to “fake” refracted detail…etc) I tried turning backface culling off which helped. but I suspect some here have tried several other tricks…
This is by far the best real-time refraction I have seen.
