Today I wanted to try some caustics effects inside Rhino with V-Ray but I was not able to achieve the effect.
I know it is possible because in SketchUp they get very nice results.
I replicated both these methods, essentially the same, but no luck.
I did enable Photo Mapped Caustics under GI Caustics in settings.
I did disable ‘Affect Shadows’ under Refraction settings.
I did increase the Caustics Subdivisions and Emit Radius in Sun settings.
I have also played with Caustics Settings quite a lot and no luck.
