Thanks, y'all. Yeah, there are some mis-matches in the composite -- the front of the train is too dark and the color temperature seems off a bit between the train and the BG. But this was done in about 15 minutes (not including modeling time, obviously!) mostly for giggles and to show the director of the movie that it will integrate reasonably well with live material. I'll be compositing people inside the train, as well -- actors green-screened, then mapped onto a plane with transparency maps to get them inside. When I have some animation, I'll post it to my website and link you all to it. - Dex Now, all I have to do is get it to move properly. Oh, yeah, and there's the scene where the brakes snap off and clatter to the pavement, just before the whole thing derails into another dimension.... :o)
