Hi, As some of you know, I'm retooling my canyon map to make it much smaller - I mean it's a LOT smaller now - as such I've gained a lot of nodes back from my original path (bring it down to roughly 125-150 now from about 300) on the old map to this version. This means that I can now be a bit more creative in some of the stuff I want to do. One of the things is this but I don't know if it can be done or not. Here's the scenario: Blue pushes empty cart to point x - cart goes into a machine - cart exits the machine but is now full of gold. Blue pushes the gold to victory or defeat further down the map. Any idea how I transition the cart from empty to full while it's being watched by the trainwatcher? Can this be done? A thought just pumped into my head as a way to do it - make another model (the gold) parent it to the empty and enable it in the machine - but would it keep all the angles etc as the cart travelled down the path?
