Back to this thread at last I've just about finished version 1 of bTraffic and am now in the process of quickly knocking out some select scenes from my proposed animation just to show how the traffic tool can work. Here are a few screenshots of various camera shots that might be used. Things will be worked up as required. (Not my truck in this scene) and an overview of the set: and here is a quick movie test of the system using high resolution vehicle models (mainly to check that they worked ok). you'll see the overtaking movement is still jerky and needs to be replaced with a smooth action. https://www.youtube.com/watch?v=E5MDStY0pKA Simon
