Hi guys,
I figured a great way to learn is work on this challenge with you all. I’m trying different methods to make the coaster and track, and kinda like the sled/car I have now. Seems to stick a little or bump into something I’m not sure. You can see in this video it suddenly stops like it hit something on the track.

Thanks for any tips and good luck to all!
hey - it’s looking good! Quite promising. Did you turn the track into a passive rigid body and the sled into an active? With a little gravity of course… 
Best of luck!
Which Software do you use? 3ds max + Reactor 2?
Looks like the simulation just stops there.

Ahh, that looks like maya. That’s exactly the problem I have too. And I found no real cure for it. The collision sim just bumps into an edge and stops there. Good luck finding a way around that bug.
Thanks guys
Yep I turned the track into a passive rigid body and the cart into an active rigid body. And yep Colt you’re right, I forgot to mention I’m using Maya. Quite frustrating at the moment since I see nothing that should be causing the bump. It’s just a cylinder for the track. I’ll try and think of another way to do this and see what happens.
