If the releaseExclusiveShapes flag is not set to true, release() will not be called on exclusive shapes.

It is assumed that the application holds a reference to each of the objects in the collection, with the exception of objects that are not releasable
|

(PxBase::isReleasable()). In general, objects that violate this assumption need to be removed from the collection prior to calling releaseObjects.
|

|
|
\note when a shape is created with PxRigidActor::createShape() or PxRigidActorExt::createExclusiveShape(), the only counted reference is held by the actor.
|
|
If such a shape and its actor are present in the collection, the reference count will be decremented once when the actor is released, and once when the
|
|
shape is released, resulting in undefined behavior. Shape reference counts can be incremented with PxShape::acquireReference().
