Rendering out a an animation with your method works but as soon as I send the scene to backburner it refuses to work. I thought it was backburner that was the problem so i did a commandline rendering and still get the same issues. The reason Why I want to render my scene with backburner is that with the scene already open it swallows up 11gb of RAM. Rendering with your script is fine but im at a point where I keep getting memory errors (basically running out of memory). This is very frustrating.
