Hi.
Sorry I don't have web space so I will try to explain the problem.
I have a static mesh cube and a rigid one cilinder. I took the python script named "constraint" from the demo "bullet_4x4_hinge_vehicle" and atached to the cilinder so the cillinder to stuckted on the cube. Then I gave to the cilinder a linear Angular velovity so it will turn in constant.
Evrything looks nice but if I leave the demo to run for some time looks like the frame rate starting to drop or the rotation of the cilinder loosing it's smouthness.
Sorry about this but I found a solution by my self.
Anyway it may help others or point a problem.
I added a new bool Property in the cilinder named "addedConstraint" so I can check If I had added a constraint before I add a new one again.
Now evrything works fine.
