hi!
In the attached file you can see a portion of an interior scene. You can look at the floor: over the parquet there are little white dots, I don’t understand the reason why they are over there.
I’ve tried to tweak with different parameters (lights, materials, GI…) with no success.
I can say that on the VrayLog message window there aren’t any warnings and errors.
Do you know which could be the reason?
Thanks a lot.
In the color settings rollout tick “Sub-pixel Mapping” and “Clamp Output”

I hope this helps, and in the future make more liberal use of the search function :), but really it’s no problem.

Thank you MoonDoggie, it works,
sorry but I remember to have red somewhere that the “Sub-pixle mapping” should remain unchecked (in fact when I chech it on the log window appears a warning), so I haven’t thought to that.
Anyway it solves the problem, thank you very much! 
P.s.
