Steve Cox' UVmapper will work as a grouping tool. Dan Wilmes' CR2Edit is incorporating more and more OBJ handling tools, too, in addition to a ton of tools for all types of Poser files, so we have lots of "plug-ins" for Poser. Steve's UVmapper Pro is not going to be free, and Dan's CR2Edit's isn't either, but both are well worth the price. And, as jamball says, the essential reason for buying those things is to make sure the programmer can afford the time to make the product even better.
