Ah, thanks, DaveRave and sprogg - those answers really help! So I do need to create some maze system (Obviously not a full maze but only what the camera sees as it goes through the animation path). And yes, I am using a background image where it helps and yes, I do go through the post-editing process frame by frame in Photoshop CS3 if it makes the final image nicer. Great advise! So I'll need to think my shot sequence carefully and break it up ino phases and then join them in video editing later. But I do marvel at some of the Hollywood movies that do this kind of scene. Theirs is a real continuous flythrough (no breakups into different camera position) from start to finish for around 5-10secs which is simply amazing. What kind of computers do they use ? Thanks guys once again!
