I've been trying to reproduce the treadmill (from this video at 1:45: https://www.youtube.com/watch?v=iLRsCtd5P9s) and I've been going through a lot of problems with the physics and the rigid body objects especially.

I've got two main problems:

  • First, when an object arrives at the end of the treadmill, it continues on the X axis instead of falling as it should do.
  • Second, I also do not understand why but the object does not fall on the treadmill but instead it stops a bit before touching it. It still move in the good direction though.

Could everyone try to help ? I tried everything I saw to resolve the problem but I can't figure it out.

Here is the file if you need it :

Thanks a lot !

  • $\begingroup$ this way it won't work. You have to use an object (solidified plane e.g.), add array modifier and curve modifier. Then it can work, if you do the right things. $\endgroup$

  • $\begingroup$ Hey, thanks for your reply. I already did that though. I created a cube that I shaped into a tile, then I added a curve and I added the array modifier and the curve modifier on my cube. $\endgroup$

  1. tap "remove rigid body world"

  2. then add it again

enter image description here

  1. delete belt down (don't know why you have there 2 belts....)

  2. change rigid body of belt like this:

enter image description here

result:

  • $\begingroup$ Okay so, it did worked well, I did as you told me to with the difference that I switched the cube with a sphere. It still worked perfectly, so I decided to save and when I saved the sphere started to go through the treadmill again... I feel like blender is trying to mock me. I aslo feel like everytime I add a new object the rigid body world goes crazy. Do I need to add all objects before and then create the rigid body world? Anyway thanks for spending some of your time for helping! $\endgroup$

  • $\begingroup$ "normally" no...but...rigid body has a cache. And that isn't that easy to delete....so....i don't know another way. In an easy setup you won't have to delete the cache at all for rigid body physics. I don't know why it is necessary in this case $\endgroup$
