Can anyone please explain.

[Tim Ellis]

Could you explain to me in "simple" terms what "large mutation probability" and "Max num consec rejections" do?

Cheers,

Tim.

Reducing the max number of consecutive rejections reduces noise, especially fireflies, at the cost
of introducing some bias into the render.

The "large mutation prob" parameter controlls the probability of using fresh random
numbers. (sorry don't know how this behaves exactly - you have to try )

btw: are you using the latest exporter?
