I tried the out the new Cycles4D renderer. In this scene tested a self made SSS shader using volume.
I used Vertex-Maps (mostly as masks) to get the detail on the edges and close to the knobs.
The Scene is lit with a HDRI and a bigger area light. Nothing too special!
Modeled in C4D R18.
Textured shaded lit and rendered in Cycles4D.
HDRI is again from Maxime Rozes free HDRI pack.
Rendered in 4K 4096 X 2160 px.
Render time was around 4h on 3 GTX 980ti
The long render time comes through the excessive use of SSS, refractive materials and the high ray depths.
Cycles 4D will be available tomorrow 15th November 2016
