PhysX Best Practices

See the following best practices when working with PhysX.

  • Colliders intersecting with terrain can result in unexpected behavior. For example, the object might rocket into space, jitter, or slow down performance. Avoid intersecting colliders with terrain. If you need to intersect a collider with terrain, use a small value for the collider size. These scenarios can be mitigated by clearing the Persistent Contact Manifold check box in the Global Configuration tab in the PhysX Configuration tool.
  • The PhysX Character Controller component must be on the same entity as the Actor component in order to work with the Animation Editor.
  • If you select the Static check box in the Transform component for an entity that also has a PhysX Rigid Body component, the rigid body behaves statically and a warning appears about the incompatibility of the PhysX Rigid Body component and the Static transform option.
  • When adding the PhysX Collider component to entities, prefer a primitive shape (box, capsule, or sphere) for the collider. These shape colliders offer better performance and should be used when possible.
