Join Aaron F. Ross for an in-depth discussion in this video Adjusting bounce and friction, part of Maya: Dynamic Simulations with Bullet Physics.
…Our simulation is looking pretty good, but…it would look better if we had a little bit of bounce on that ball.…So let's add bounce.…In Bullet, bounce is known as a restitution.…And it needs to be added to both of the colliding objects.…I'll select the ball and the ground plane, go over to the channel box and…scroll down.…And you'll see Friction and Restitution.…Friction is set to its maximum of one by default.…Restitution is bounce, and with the restitution of zero, we get no bounce.…If we set restitution to its maximum of one for…both the ball and the ground plane, then we would get some strange results.…
Press Play and you'll see the ball bounces up very high and…if I dolly back a little bit here we can see that really clearly.…That's not a realistic result.…The ball is not obeying the laws of physics.…There's no way it could bounce up higher that its initial position.…What we'll do is just reduce that restitution to…a lower value of let's say 0.8.…Rewind and play back.…And now we're getting a much better result.…
