Problem with white dots

Hello everybody, I’m noob with vray, just testing a scene and some parameters, I’ve watched some videos and read some tutorials and tips about how to render a scene and here I attach the result, I have a white dots and I don’t know why, sub-pixel color and clamp out are ticked, any idea of how can I solve this or what shall I adjust?

Thank you so much in advance.

Could you shere with us your render settings, screenshots would be helpful. It looks like you are using Progressive Image Sampler with perhaps the default settings. For a start try increasing the Render time of the Image sampler to higher values. For more information about it you could check our online help documentation: Chaos Docs
