Animate an object array along a path with curve modifier I'm working on an industrial conveyor belt and trying to animate it but can't figure out how to make it run.

It's a single object with an array to multiply it, deformed with a curve modifier.

I tried pretty much avery axis to move it, but it either stays still or move on the side.
You can parent the belt to another object (an empty for instance).

Then simply move the empty in the appropriate axis (along x in the blend file attached below). 



You can also move the object itself along the same axis.
