Hi all
Not sure if and why I'm having such sever stair-stepping artifact,
it is maxwell 3.0.99.4 beta.
The bump seems to destroy the smoothness of the sphere...
with maya subdiv preview or maxwell subdiv it goes away but leaves a harsh transition from light to dark.
what am I missing?
thanks

Bump is a fake effect for simulating displacement on the surface. If you have sharp transitions even after subdividing the surface, it means your bump value is just too high.

gotcha, thanks.
