The character just keeps falling through the floor (which is static), i can shoot rigidbodys against the character and they bounce off it so the collision object is there, but the character is unaffected.
What more if i shut off gravity and set fallspeed to 0, the character still keeps falling.
I've tried all sorts of values on the colisionflags and collisionmasks, including the vaules used in the demo, and my own collision mask.
Using Bullet version 2.73.
Edit: solved the problem, it seems I used a different BroadphaseInterface in the character then with the other objects.
