Dielectic material to become black at high settings.
I want to render a glass of champagne and a display of these settings under the render (mental ray rendering image) glass is black but retains all of its reflection.
2500x2200 200dpi TIFF uncomp.
Max Sample Level 2
Mitchell 4.0 4.0
Max Trace Depth 52
The rest default.
Lighting, two Area Light, photons do not use
When the value of Max Sample Level 1, everything is fine
Thanks in advance
