stretching problems with curve modifier I am building a tank tred using a combination of the array modifier and curve modifier.  The problem that I'm having is that the tred is experiencing uneven stretching when it bends around the corner wheels.  Is there a way I can fix this  (maybe something is wrong with my bezier curve?)

Attached are the curve points and also the settings on the tank track
Consider a path constraint.  You may want a script for placement of objects.

Consider a rigid body constraint.

Neither of these are trivial to do from starting point zero.

Curve Modifier by comparison is less work.
