Here is some of my material RnDs which created by Corona.
Very nice.
How did you get the internal cells for the crystal materials, did you cut the poly with some sort of veronoi first?
Yes, I fractured geometry for crystal type materials.
Any chance you would consider sharing the Corona / 3ds Max version of the shaderball scene here? It would be very much appreciated 
The official Corona Shaderball is now available here for 3ds Max and C4D
