Move object array along curve

Question

I have a simple mesh that forms a belt around a BezierCircle with the help of an Array and a Curve modifier. I want to move the belt forward and animate it.

The common way to do this is to simply move the object, but when I do this, I get:

I also already tried Follow Path constraint and duplication frames; neither worked.

Answer 1

Just found it out myself: The curve was not looping.

• Move the object so that the error is clearly visible.
• Select curve, go into edit mode.
• Find the segment where the array modifier quits the curve.
• There, look for the ending of the curve (The segment is not attached to its beginning) and select it.
• Tool shelf, "Toggle Cyclic".
