Quote - It occurred to me that empty morph channels should probably be inserted at the beginning of the channel list, not the end, although I'm still a bit fuzzy on how the whole channel order thing plays out.

I'm fuzzy on that myself, but I do know that in a cr2 the order of rotation channels relative to one another is relevant, as is the whether the rotations come before or after the translations. I don't think the order of translation channels relative to one another matters. I think that targetGeom should come above transforms and JPs. I haven't seen any evidence that the position of valueParm is relevant, but feel it is probably best to put them above transforms and JPs.

A geomChan is always placed at the very bottom of the stack in my experience, though I don't know it that is necessary.
