This isn't working?
I have a group with polys in it. I tried
mgAttach(lod, group)
I also tried iterating each poly on the group and just attaching the polys to the lod but that didn't work either.
I would bet that the group you are trying to attach is already attached to another node. If this is the case, you must first un-attach the group with mgDetach(rec)
