Yeah - that's an interesting problem.

They come though un-transformed...it has to be like that for many reasons.

The ODE collision library must have some mechanism for indicating that
objects are stuck under a transform.

Yes - it does.  But that array isn't transformed by any ssgTransform's
above them in the tree because that would preclude moving parts in the
model.

There are actually several different leaf nodes that operate in different
ways.
