Flickering foliage

Thanks Svetlozar.

I agree in that it's a AA and filtering problem.

I would
-set filtering to None if you have opacity on the leaves.
-Render trees and 'the rest' separately and compose later. (I now use vray's new feature "render mask" in selected mode)
-AA adaptive 1/4 for anything but trees and 1/32 for trees
-noise threshold: 0.008 for both passes.
-filter: soften
Note that changing the noise threshold in just 0.001 makes a big difference in time/quality. It's very sensitive.

If it's a night scene, bake as many lights with the irradiance map and turn them off when rendering.

Thanks so much Guido. I will also try your settings.
