Cryptomatte bug when Sequence rendering In Fusion #94

Closed ascodrani closed 5 years ago

ascodrani commented 6 years ago

Hi, I have this sequence that I'm compositing in Fusion with all my AOV comming straight out of MAYA rendered with Arnold. While I'm compositing in Fusion 9 everything works fine, when playing back my masks of the cryptomatte work without a problem. But at the moment I am going to render out the image sequence out of fusion it goes completely nuts. For a random amount of frames it will work as expected but then at some point my cryptomatte is going to "fuse" with other masks i have on a completely different spot in my network and combine them or substract with each other, which makes it very disturbing to say the least... Tell me if you need any extra information!

Thank you very much in advance! Cheers, Antonino

Hi @ascodrani

Is there any chance that the renders are using 90%+ of your memory?

There is a known bug that when Fusion renders images out with Cryptomatte, and the Lua memory buffer goes too high, artifacts happen such as masks vanishing or even other Cryptomatte masks appearing on the wrong place. More info in #46.

Cheers Cedric
