I've created a conveyor belt out of single links using an Array modifier and then a curve modifier to get a conveyor shape. Additionally I've added a keyframe animation on the Y coordinate with a Generator which produces a constant movement of the belt.

Blender setup

The problem is, that the little white-green package falling on the belt does not interact with the moving belt: It falls through and is not moving as you see below (there is an additional passiv black cube below the moving white links and this is the object the package collides with).

Moving belt

The package is an active rigid object, the belt a passive animated rigid object. Potentially this has something to do how I created the curve of the belt: I used a circle, selected "Curve from mesh" and applied the curve modifier to this curve:

  • $\begingroup$ I think this is what you've got close to anyway, but if it helps... blender.stackexchange.com/questions/155009/… - In a later version of this I placed a rigid body plane along the belt to catch the cube. I see you have a cube under your belt also. $\endgroup$ – Edgel3D Sep 27 at 6:01
