XNA 4.0 Model into parts

Question

is there a way to split a .fbx model into parts, and move those parts individualy in XNA 4.0 ?

Thanks

Perhaps when you draw each part you could give each one it's own world matrix, remembering that each part is still offset from the origin of the model as a whole.

foreach (ModelMesh mesh in model.Meshes)
{
    foreach (ModelMeshPart part in mesh.MeshParts)
    {
         ((BasicEffect)part.Effect).World = ((Matrix)part.Tag).worldMatrix;
         ((BasicEffect)part.Effect).View = viewMatrix;
         ((BasicEffect)part.Effect).Projection = projectionMatrix;
    }
    mesh.Draw();
}

Of course, this means that you'll need to find a way to identify each part and assign each of them their own special worldMatrix, because the Tag is always null by default.

Besides that, the only other solution that's immediately appent to me is to export the objects individually and treat them as their own entities.
