What happened when you loaded that cr2 and then exported the geometry is that Poser used the cr2 to get to the copy of the geometry in the geometries folder and copy it from there. If there hadn't been a copy in the geomtries folder, you wouldn't have been able to do it and you wouldn't have even been able to load the cr2 in the first place. Or possibly that particular cr2 was one that had "embedded geometry", meaning that the obj file is actually contained within the cr2 itself. If you made your model with separate geometry then you don't have to worry about that. MAT files and poses are always safe. They never carry geometry (that's not quite true but I won't get into the exceptions because only people that really know what they're doing can make those and those people know enough not to compromise your copyright). Sometimes third party cr2s can wind up containing geometry if the maker wasn't all that expert and did something like creating new groups. It's easy to check this if you understand the basics of cr2 structure. Look for obj file style code in the first part of the cr2. In most cases when people make a cr2 to go with your model there's no problem. In general, it's a good thing if people make and distribute free add-ons for your stuff. It makes it more versatile and helps advertise your product.
