Pixel clamping

In addition to sample clamping it would be great to have a pixel/camera sample clamping for the same reason, reduce noise.

For some time Vray only had a check-box to clamp final camera samples to 1 or sub-samples with another check-box. It was the only way to have proper antialiasing around visible area light

Clamping primary and secondary sample is great BUT, it doesn't prevent pixels to be over-bright, also, if you clamp too much, it darken the scene.

This new option, should be just another slider below the two existing one and set to zero by default

Optional and if it's possible, a check-box should give the option to affect the passes(diffuse direct, indirect, glossy etc)

I can spend time with a developer to speak more on the subject or create exemples showing the benefits

you could post screenshots here too, to make it clear what the advantages would be

well basically it's less noise and almost zero firefly within a few passes (also no hard caustic). Don't have time right now sorry
