Friction issues....or something else?

I’m working on a project for moving things around with a fork lift. I added a Physic material to the box I’m moving and to the forks. If I set the friction low, like .01, then it works pretty good when raising the forks, but the box slides around on the forks when the forklift moves. If I set the friction higher, say .5, or 1, then the box starts bouncing around and bounces off of the forklift when it’s starts lifting. Any ideas on that one? Maybe I need to change the friction in code when the forks aren’t moving, if that’s even possible? Just isn’t working anywhere near like real physics.
Thanks,

Got it working pretty good. I was changing both static and dynamic friction values at the same time. I set Dynamic to .01 and static to .99 and that’s working fairly well.

Yes, unfortunately friction in PhysX is mostly trial and error. There’s no correspondence among material’s coefficient of friction and the actual behavior. The results depend on the shape of the colliders and the number of contact points.
