Solved on the normal OGRE Forums...

I am trying to make a Newton's Balls demo thingy using OgreNewt.

I am not sure what I am doing wrong, but here is the effect:

And here is the code:

//create the balls and stand for physics

	Entity* theBall;

	OgreNewt::Collision* col;

	for(int i = 0;i<5;i++)

	{

		theBall = mSceneMgr->createEntity("TheBall"+i, "MetalBall.mesh");

		mBalls[i] = mSceneMgr->getRootSceneNode()->createChildSceneNode();

		mBalls[i]->attachObject(theBall);

		mBalls[i]->setPosition(Vector3(2-i,0,4.5));

		mBalls[i]->setOrientation(Quaternion(Degree(90),Vector3(1,0,0)));

		

		col = new OgreNewt::CollisionPrimitives::Ellipsoid(mWorld,Vector3(1,1,1));

		pBalls[i] = new OgreNewt::Body(mWorld,col);

		pBalls[i]->attachToNode(mBalls[i]);

		pBalls[i]->setMassMatrix(1,OgreNewt::MomentOfInertia::CalcEllipsoidSolid(1,Vector3(1,1,1)));

		pBalls[i]->setPositionOrientation(Vector3(2-i,0,4.5),Quaternion::IDENTITY);

		pBalls[i]->setCustomForceAndTorqueCallback( BallScreensaverApp::physicsGrav );



		col = new OgreNewt::CollisionPrimitives::Box(mWorld,Vector3(1,1,1));

		pStandL[i] = new OgreNewt::Body(mWorld,col);

		pStandL[i]->setPositionOrientation(Vector3(2-i,-2,4.5),Quaternion::IDENTITY);

		pStandL[i]->setCustomForceAndTorqueCallback( BallScreensaverApp::physicsGrav );



		col = new OgreNewt::CollisionPrimitives::Box(mWorld,Vector3(1,1,1));

		pStandR[i] = new OgreNewt::Body(mWorld,col);

		pStandR[i]->setPositionOrientation(Vector3(2-i,2,4.5),Quaternion::IDENTITY);

		pStandR[i]->setCustomForceAndTorqueCallback( BallScreensaverApp::physicsGrav );

		

		col = new OgreNewt::CollisionPrimitives::Cylinder(mWorld,0.05,4);

		pLineL[i] = new OgreNewt::Body(mWorld,col);

		pLineL[i]->setCustomForceAndTorqueCallback( BallScreensaverApp::physicsGrav );

		pLineR[i] = new OgreNewt::Body(mWorld,col);

		pLineR[i]->setCustomForceAndTorqueCallback( BallScreensaverApp::physicsGrav );



		//bJointL[i] = new OgreNewt::BasicJoints::BallAndSocket(mWorld,pBalls[i],pLineL[i],Vector3(2-i,0,4.5));

		//bJointR[i] = new OgreNewt::BasicJoints::BallAndSocket(mWorld,pBalls[i],pLineR[i],Vector3(2-i,0,4.5));

		//tJointL[i] = new OgreNewt::BasicJoints::BallAndSocket(mWorld,pLineL[i],pStandL[i],Vector3(2-i,-2,4.5));

		//tJointR[i] = new OgreNewt::BasicJoints::BallAndSocket(mWorld,pLineR[i],pStandR[i],Vector3(2-i,2,4.5));

	}

It looks to me like there is some sort of offset problem. I have no idea what I am doing wrong and the debug boxes for OgreNewt will not turn on for some reason. What do you guys think?
