v-ray rendering weird random blue dots!

[boogotti]

hi everyone,
i got a problem with vray, when ever i'am rendering my car in vray (using vray 1.47) it seem's to render weird blue dots around the wheels. i have checked the shader of the wheel and its fine. i checked the render passes there all fine apart from the reflection pass.
This problem started when i had the wheels as one file and the rest of the car on another file. The wheel was rendering fine on problems. But when i megred the file as one thats when the problem started. don't now if that has anything to do with it?


here are the images of what is happening. thanks

I've gotten the same thing, a couple of times--but not to that degree. Doing a car render I had a couple of blue spots on the chrome mirror and wiindshield wiper. And yesterday I had some at the edge of a pond in a building exterior render--both using vray 1.46. I don't know what causes it and would like to find the solution as well.

i found out what was causing the problem after doing some searching around. this tends to happen to objects which are grouped or don't have uvw maps.

what i did was ungroupred the wheel and linked it and it renders fine now!
