Real-Time Physics Simulation Forum

Hi I have made a soft body tire which behaves fine on collison but the problem is how do I add a rigid body wheel in the center I tried Constraints but this dose not work. I also tried this but no luck

Tire->setMass(1, 2.f);

Tire->appendAnchor(1 ,btRigidBody* Wheel, bool disableCollisionBetweenLinkedBodies=false);


Also is using SoftBody tires with constraints to intensive in most game applications?

Thank You, Bullet Physics is truly Awsome!!
