max bounces in superfly settings
What exactly means "Max bounces" ( maximum of total Bounces)
Does that mean all bonces together are not more than 4 in this exaple. So it makes no sense to make 15 transimission bounces if max bonces is 4?
Yes all bounces together are limited by that. It makes sense in the same way that making an object invisible makes sense. You don't do final render with that - you do test renders with fewer bounces overall, giving a speedup for a draft render.
Then you raise it back to 50 or whatever, and all the individual values below it will be used for your production render, because those limits are reached before 50.
@bagginsbill Thank you very much for your answer :-)
