Animation render artifacts, assets turn black or lose there materials

[richard_harling1]

I have an increasing issue when rendering animation sequences where assets either lose their material or turn black for a frame several times during a rendered clip. The issue doesn't occur on the same frame if I render the clip several times.
This occurs regardless of render settings
Any help would be awesome

See attached
Frame 1, normal, frame 2 the issue circled in blue

Hi Richard, thank you for bringing this to our attention, we will investigate this and make a report. Would it be possible to share your scene with us since it would help troubleshooting this faster?

Best,

Sure thing, another problem I am now having is when rendering out a sequence the processing almost consistently hangs and doesn't finish...

Sorry to hear that, this is highly likely a case where the system is running out of resources we are working on improving on warning the user for such cases as well as hopefully handle the exception more gracefully. EC-1583
However, it would be prudent if we also verify internally that this is indeed the case after troubleshooting your scene.

Ok thanks George, currently when rendering Envision is using a quarter of my RAM... standby, uploading files
