Does this Saguaro have "arms" you can rescale separately - and move up and down? (didn't see this info on the RDNA page) The Saguaro models I have now are all static props and I have been very frustrated in trying to make a group of them (they often grow in groups) - with different looks to them. There are only so many times you can rotate the model in one scene! If not in this pack, perhaps in the higher-res pack that comes out later? (Pretty please!!) :-) thanks -dg
