Bulletphysics body goes through floor

[white_waluigi]

i have the following problem: I'd like to use bullet physics for moving the Character around. so far i have a severe problems with jumping: if i fall on the ground, the body (the Character) sinks into the ground for a couple miliseconds. the longer he falls, the more he sinks. Im using a gravity of 20, a cylindershape, and a groundplane with sleeping thresholds of 0,0. is there any way to fix this?

Maybe some code showing how you add your objects to the scene would help, but first, try using a box shape with small height instead of a plane for the ground.
