Hey folks I'm running C4 and I've been doing some tests with the motion path s and the new landscapes and the new vector motion blur and all... The thing is I've been running this render now for close to 72 hours! I've paused it and re-started it and every time the processor usage spikes to full... then after about an hour or so it drops down to using half the processor. (Or, more accuratly, it uses one processor of the multi-threaded P4 3Gig with 1Gig RAM.) Now... I know I'm asking a lot, (vector motion blur adds 2 extra frames to every one 'actual' frame,) and I am using sky light. But EVERYTHING is set to the lowest settings of the renderer.
