About This File
Here's a 23 minute tutorial on using the Align to Spline expression tag. Covered:
Animating all the properties
Rail splines and banking
Getting constant speed by changing spline interpolation
How to stop flipping using rail splines
Using a Null object to change object orientation
Sorry about the file size. The tutorial covers animating so I have produced the video with a higher frame rate than normal. Although recorded with R13, users of previous versions should have no problems following along.
mp4 format. Play with any media player. Also included is the cartoon plane.
