[Video] Dynamically Combine Meshes In-game to form new composite Physics Shapes!

Hello, i try to utilizie your physics constraint tutoria:

this is effect:

And I am totaly not know why my constrained blocks are that much flexible and not solid like in your videos

This is how I set limits with your functions:

SetAngularLimits(ConstraintInstance, 2, 2, 2, 0, 0, 0);

SetLinearLimits(ConstraintInstance, false, 2, 2, 2, 100);
