Hi, I basically want to create a matrial that, rather then loosing energy per bounce, will increase it. I've tried:

phy set material restitution 1, 1.2
phy set material dynamic friction 1, -1.0

But of course that would be too damned easy, instead I get an out of parameter range error.

Is there any way of creating a material that adds to the objects speed rather then subtracts from it?

Technically no material can increase energy per bounce. It breaks the laws of Physics (Dp or real world) you should add energy by applying a force

Maybe just apply a force on the y axis when the object collides with the floor/surface?

Naw, I'll have to work out the new angle on all axis after the bounce and compenstate for both loss of speed and add a manual acceleration curve. So troublesome, but hey. Whatever.

It would be good to be able to defy the laws of real-world physics. But maybe PhysX is designed to make sure you can only stick to a real-world model.

Which is quite silly when you considering it's being made for games. There's alot of science fiction stuff that defy's gravity entirely. Repellant force fields, anti-gravity devices, super-conductive surfaces, etc. Yes it's nice to have visually realistic physics, but it would also be nice to have a flexible engine that goes beyond that into the world of fiction as well. Seeing that most games are set there. But I guess Ageia where too tightly focused to consider that.
