(Fixed) [HOU-1707] nan pixels in filtered renderchannels

[LeoYfver]

We get nan pixels in renderchannels that are filtered. Specifically zdepth filtered and normals filtered.

The problems seems the worst with motionblur enabled but seems to still exist without sometimes

Included a simple scene

the image is the normal renderchannel

Hey, Alexis,

got the same behavior here. I'll try to find someone from the Core team to take a look and keep you posted with any progress. I noticed this only seems to happen if the Shutter Efficiency is exactly at 0.5 - offsetting it even with 0.001 seems to resolve this - I've only rendered about 100 or so frames so it's possible I'm wrong here, though.

All the best!

thanks! got it even when the motioblur was off just alot less often, would guess its the same with shutter offset

Hey, LeoYfver ,

the problem should be resolved starting with tomorrow's nightly builds.

All the best!
