Summary#

Rigid bodies have to be UsdGeomXformable prims.

Description#

The UsdPhysicsRigidBodyAPI has to be applied to any UsdGeomXformable prim so that the xformOps can be authored when simulation steps.

Why is it required?#

  • Assets with UsdPhysicsRigidBodyAPI define a rigid body for the simulator. Prims with this API will have their xformOp attributes updated after each simulation step.

Examples#

# Invalid: UsdPhysicsRigidBodyAPI applied to a Scope
def Scope "scope" (
   prepend apiSchemas = ["PhysicsRigidBodyAPI"]
) {
}

# Valid: Rigid body and collision on UsdGeomXformable
def Cube "cube" (
   prepend apiSchemas = ["PhysicsRigidBodyAPI", "PhysicsCollisionAPI"]
) {
}

How to comply#

UsdPhysicsRigidBodyAPI must be applied to a UsdGeomXformable.
