Material zones are in both, the obj file and in the cr2.

You will have to adapt both if you want to get rid of a material zone.
I merge material zones, and always do it in both.

That is why it is not so easy to do it inside Poser.
Poser would have to adapt the cr2, but also would have to save a fresh obj file.
