Hi all this is my first post and my firts render with vray for rhino: Van Der Rohe Chair



there are 2 rectangular light on the right/left with different multipler

settings:
1 irradiance map
0.8 light cage

adaptive dmc min subd 1 max subd 50 noise threshold 0.005

dmc sampler adap 1 min samples 8
noise thresold 0.01 subd mult 1

color mapping reinhhard burn value 0.85

irradiance map
- 1 max -3
50subd samples 20


the problem is the reflection of white rectangular light
i have incresed the subd of reflection of chrome from 8 to 20 to 35 but is the same always aliasing

Re: aliasing on reflection

Image is burned from the light intensity. Either adjust that, the exposure or as a quick-fix; Turn on Clamp Output and Sub-pixel Mapping in the "Color Mapping" section.

Re: aliasing on reflection
