body->setNode(node) or node = body->getNode()?

Hi.
Here's the code.

body = mScene->createBody("monster.mesh",new CubeShape(0.01f),Vector3(500,40,800),"mass:10");
pMonsterNode = body->getNode();

I found that the pMonsterNode's center is not the same as the entity's.
Another problem is the setNode();
When I use the code above I can move the entity by moving the pMonsternode.
But when I use

body->setNode(pMonsterNode);

I cant move the entity when the pMonsterNode is moving.

How to adjust the entity's center to the node's center?
What's the diffence between body->setNode(node) and node = body->getNode()?
Thanks.

You should adjust the mesh center in your modeller or use an external tool such as MeshMagic which can be found on the main forums.
