I’m rendering an animation with Cycles, and I’ve got a hard deadline I have to have it done by.
Is there any reason I can’t do a “safety” render at, say, 100 samples, and then if there’s time, render the animation again - this time with the Sampling Seed set differently - and then just comp them together?
I find myself wondering why the Seed value isn’t automatically animated / randomised. I mean, under what conditions would you ever need the Seed to be repeatable? I’ve already discovered that quick preview renders [of animations] with low samples benefit enormously from having the Seed animated. You get fizzy noise that looks like film grain, rather than what looks like an ugly static dither pattern over your animation.
Might have to ask on the Python forum how to create a driver that always gives you a random seed (eg one that takes, say, time of day into account)
