if I understand this correctly, there is no real need for the leaf nodes
with textures to be below the LOD's, yes ? Then you could put them in their
on (sub-)graph and make that a child of the node that is also the parent of
your top LOD, like this
Node (with GroupCore or SwitchCore or
...)

Node (with GroupCore) Node (with LOD

LODs, ...)

that's basically what I describe above.

Hm, (sorry, I know this may sound insulting, but I can't think of another
reason) did you add texturedCubesRoot to your graph, i.e. is there a line
like:
someNode->addChild(texturedCubesRoot) ?

sorry, don't know that one.
Hope it helps,
