Just a note to anyone else who might be having issues with frequent crashes due to your sequence being too bonkers- try exporting as a PNG sequence instead of AVI. That way, you can keep the frames that you didn’t get to. You’ll have to bring your sequence into a video editor to push them back together, but it will save you time in the end. EDIT: Also, be sure to unplug any HMD that you might be using prior to starting your render.
