Conveyor belt object fall through problem I watched a tutorial video and tried to learn how to make a conveyor belt. Everything went well until I put a cube on the belt. Somehow, the cube just fell through the belt. I googled a lot even watched other tutorial videos but still got the same result.
Here are the images of my object rigid body settings:

Any advise as to what I'm missing or doing wrong? Thanks in advance for your help.

It's probably your margin settings that are causing this problem. Increase it until you get it right.
