int32 RenderWarmUpCount
The number of frames at the start of each shot that the engine will render and then discard. This is useful for ensuring there is history for temporal effects (such as anti-aliasing). It can be set to a lower number if not using temporal effects.
This is more expensive than EngineWarmUpCount (which should be used for particle warm-ups, etc.)
