I have adapted an old composition with some marbles. I removed all the lamps and just used an HDRI image to illuminate the scene. I just have some problem to get the caustic as I’d like. Anyway, the result is ok for now.
Composed with Blender
Rendered with Yafray
Time for rendering : 1h35 on a P4 3.2 HT
As usually, C&C are welcome.
