Pulley with rope animation

[desiree_schneider@hotmail.com]

If you construct pulley with several convex objects (same as chain in chain sample), it should work.
But in order to make it really precise, you'll need to make series of tests of trials and errors... 
...or be more knowledgeable then me.
(I've never tried something like this, but it's interesting question) 

Keep in mind that mass parameter only mean force that one particle pushes the other.
It doesn't mean that object is heavier... for that... you'll need to disable PhysX default gravity, and enable separate gravity for each different sized object.
As I said, it's fairly simple to create something like this, but if you want it to be really precise, then it's much more work.

That's my 2 cents, Tyson, or someone else, might  give you much  better advise

Hey Hey
many thks for your answer. The teacher of the 3D course told me as well, that you have to cheat this animation. So what I do not understand how to adapt the chain tutorial due the chain tutorial has a Tyactor and no splines. So Pulley with rope are normally done with splines. That is making me confusing.For your help I would be very grateful... Desiree
