using makeCoredNode<T>(&core) creates a new node and new core of type T
and stores a pointer to it in the argument. Since you already create the
cores by hand you should use makeNodeFor(NodeCore* core) instead.
Alternatively remove the lines that create _material and _transform and
let makeCoredNode create them.

hmm, I don't see anything wrong with the code you posted (unless it has
to do with the double creation of some cores mentioned above). Are you
sure pose and q1 to q4 are updated so you actually set new data when
calling setPose?
