…that is easier to do in DAZ Studio than in Maya!
Okay, maybe not. I did have to write a script to call the “photon” hider and a light shader to actually cast caustics; and I had to add photon emission to my directional lights and suitable shading models to my refractive/reflective surface shaders. But really, out of all the 3DFM (3Delight for Maya) how-to’s, this one gotta be the most complicated.
Oh yeah, test renders. Here they are. The vase is “glass”, the Stanford dragon is “water” – but that’s just the photon shading models used for caustics; the refractive/reflective shader I use is the same (absorption colours may differ, but not too much; and yes this all will be available, maybe even the vase if anyone needs it).
