The possibility to correct colors for all objects within the FP panel is a great new feature!
However, I find it difficult to get pleasing results when changing the saturation in the FP Color Correction Rollout.
So I did a test sequence with a vegetation patch (see attachment):
on the left side the saturation value (in %) is changed directly in the Vray material via a color correct map.
The right patch shows the result using the saturation correction in the FP Rollout.
Using FP702b, the color doesn't only desaturate but also becomes lighter, which doesn't give very pleasing results, especially for vegetation.
