So here's the problem. I'm trying to build a roller coaster track, but I run into problems whenever I try to build a corkscrew or a loop. I'm joining a bunch of splines together, then I'm going to clone the track geometry onto the spline. (I'm not dealing with the rail spline or banking yet, just the path of the track) I need the helix spline to run in a straight line at the beginning and at the end of the spline, but curve in the middle. I can get one or the other (by adjusting the Height Bias to 0% or 100%), but not both. I've tried adjusting individual points (always looks like crap), creating a spline from scratch (still crap), formula spline (no idea what I'm doing with that), and using a deformer on 3/4 of a circle spline. I can't seem to get anything to work. Any ideas?
