I think I may have noticed something like this at one time but didn't really think anything of it. It makes sense in a way. I think A lot MATs use the format ":Runtime:Textures..." If Runtime were the default starting point, why include it? The default is apparently the Poser root folder. Is there method in the madness? The original Poser design pretty much limits faces, characters etc. to the one runtime folder--those are the things that show up in the library. Textures and presumably geometry could possibly be located elsewhere. So, in theory, you could have a Runtime_2:Textures... or Runtime_2:geometries... setup, within the Poser root and without going to absolute paths. Why, I have no idea except maybe to avoid overload in those to catch-all folders. I'm in the cotton headed phase of some winter illness so if none of this makes sense, I have an excuse :-)
