I know your probably getting tired of this thread but please be patient with me.

OK. I have noticed that when all Runtime folders, primary and externals are loaded into Poser an item within one runtime can find the necessary geometries it needs located within a separate runtime folder. So, just so I don't miss anything, What you are doing is creating two separate external runtime folders; One for textures and the other for geometries. And all of your other external runtime folders do NOT have geometry and texture folders within their runtime file trees. And when Poser 7 has all the external runtimes loaded, there are no object or texture reference issues?

I experimented by copying an entire custom character directory to its own external runtime. When only that runtime was loaded into Poser, the app couldn't find its object file data but when I had both loaded into Poser, there was no such problem. Look, I hate to be pulling this noob crap but I have to be sure before taking any action. It's more than just my time but I have a lot of money rapped up in these files as well. If I sound like a noob then talk to me like one but please understand my fear and reluctance. Besides, I am not a program expert, I'm an artist. I never said I was anything more than that.
