Okay so I've checked out several tutorials I have seen for tank treads. They all basically involve creating the curve in the shape of the treads, then attacking a single tread-link to the curve as a motion path. Then duplicating the the tread and the path and moving the uValue of that tread a bit, then doing it over and over until the entire path is filled and they are all spaced correctly.
But the biggest problem is the way the individual treads follow the motion path. The best way to do it appears to use the 'Normal' World Up Type, which means that the tread's upvector points toward the same direction as the curve's normal at that point on the 'u' axis. The problem with this is that whenever the curve has a part of it that is concaving so the normal faces towards the 'inside' of the path, then the treads flip 180* at that point when they get there.
This all sounds confusing but if anyone has any ideas on how to control the motionPath stuff better I would like to hear it. Thanks
