artifacts in the image

Hi, studiosachin !
The demo version handles Vray settings until 800*600... if your image is larger, settings are wrong..
Anyway, in rare cases this specific bug have been raised by some beta testers...
I'm actually working to isolate ank kill this bug..

The white dots in your image are surrounded by black circle.
This means that subpixel mapping is ON (color mapping section)
try to unchek this option to see if it helps.

i give you some news about that soon.
if you're interested by sending me a scene containing this pb (just the left wall for example), just don't hesit !

are u in LWF or classic workflow ?
