@shvrdavid Yes totally random, I have larger scenes that work fine and even the same scene will work. I REALLY should have mentioned this is in SuperFly renderer. I have 32gb of memory and all runtimes are on local drives and the app is running with effective admin rights. The missing shoe was a separate figure. What we could really do with is a viewer for the queue so at least we could see if there were issues before waiting 2 hours for the renderer to complete. Amanda
