[Max] Bug Reporting / Suggestion for noise evaluation to prevent premature renders
« on: 2018-08-29, 20:39:57 »
Hey guys,
I run Corona on our farm and some times it happens that a client uses just noise limit to stop a frame and we get some frames finishing faster than
they should be.
I've discussed with Thomas M. Grimes a few days ago at D2 in Vienna about this issue and he mentioned that he was able to reproduce and that's a known bug
which has not been addressed so far.
My suggestion is that instead of sampling every X passes (5 is default) is that you sample every pass for noise limit, and every X passes you do an average
of noise collected from the sampled data. In this way if there's a big difference between sample 4 and 5, it can be filtered out by doing math on curves, so it should give less false
stopping signals.
Not sure what is the cost of sampling every pass, but at least it will not stop frames unexpectedly and people can rely on using noise level in their animations
or still renders.
Let me know what you think.
Thanks!
Alex
