Character controller Implemantation

Hello ! I'm trying to implemante a Character controller, I'm not using the wrapper, I use directly PhysX. But i've some problems, my Critter::Body or NxOgre::Actor are not detected in the callback, just my scenegeometry. Then here is how I proceed :

Create a body :

   NxOgre::ConvexDescription description(scaledMesh);

	Critter::BodyDescription bodyDescription;

	bodyDescription.mMass = mass;

	bodyDescription.mGroup = GROUP_COLLIDABLE_PUSHABLE;

	bodyDescription.mAngularDamping=0.5;



	NxOgre::Matrix44 mat = nxTransformMatrix(pos, rot, Ogre::Vector3(1,1,1));



	Critter::Body* body = mpv_PhysicMngr->getPhysicRenderSystem()->createBody(description, mat, fl + ".mesh", bodyDescription);

Create the CC :

  NxCapsuleControllerDesc desc;

	desc.setToDefault();

	desc.skinWidth = 0.1f;

	desc.radius = 1; 

	desc.height = 3;

	mpt_OffsetY = desc.height/2 + desc.radius;

	desc.upDirection = NX_Y;

	desc.slopeLimit = 0.7;

	desc.stepOffset = 0.5;

	desc.position.y = 50;

	desc.position.x = 0;

	desc.position.z = 0;

	desc.climbingMode = CLIMB_CONSTRAINED;

	//desc.interactionFlag = NXIF_INTERACTION_USE_FILTER;

	desc.callback = &mpt_Callback;



	mpt_Controller = manager->createController(mpt_PhysicScene->getScene(), desc);

	mpt_Controller->setCollision(true);

To move the character :

  mpt_Controller->move(dir, COLLIDABLE_MASK, 0.000001, flag, 1.0);

	if(flag == NXCC_COLLISION_DOWN)

		mpv_Jump.stopJump();

The physic update :



  mpv_PhysicWorld->advance(timeSinceLastFrame);

	mpv_Manager->updateControllers();

And then, the callback :

class CCCallback : public NxUserControllerHitReport

{

	virtual NxControllerAction  onShapeHit(const NxControllerShapeHit& hit) 

	{ 

		GameFramework::getSingletonPtr()->mp_Log->logMessage(hit.shape->getActor().getName());

		return NX_ACTION_PUSH;

	}

	virtual NxControllerAction  onControllerHit(const NxControllersHit& hit)

	{ 

		GameFramework::getSingletonPtr()->mp_Log->logMessage(hit.controller->getActor()->getName());

		return NX_ACTION_PUSH; 

	}

};

As you see, at the moment I just want to log the name of the shape who is in the callback, and my Critter::Body or Critter::Actor never appear...

Do you have any idea to help me ?

Thank you in advance !
And sorry for my bad english...
