Weird white reflection noise
- 
 Hi all, Could any one try to help me find out what's wrong with my VRAY here? 
 I working with Sketchup 15 (64 bits), Vray 2.0.The is my problem: some random times, it appears that the light reflections create an unexpected white noise on SOME materials, not all of them. See attached. I checked a lot of other topics, tried to subdivide all materials, tried all kind of DMC options... When the output resolution is huge, the white dots are smaller but still here. As you can see, the materials are not pixelated that much, just these weird white reflections... I can't explain how this is possible. It makes me really sad! I would appreciate if someone could just tell me what parameter to dig into. Thank you all very much. 
 Best,
 V.
