When rendering in TG4 it does seem that I'm running out of RAM. I've attached a screenshot of the error message for reference.
Strangely, when I send it to PixelPlow, using TG4, I get the following message:
"Your job, job92156621567420, has encountered multiple slice errors during rendering
Warning: SetParamFromString: Unknown parameter: "minimum_threads" in class: renderC:\Windows\system32>IF NOT ERRORLEVEL 0 set retvar=-1073741819"
I don't really know what that means, but I've sent a message to PixelPlow support asking what I can do to resolve the problem on my end.
