Regarding geometries... I don't know (yet) whether the situation has been improved in Poser 6, but my biggest nightmare in the past was that Poser 5 certainly does lose track of any moved geometries (which have absolute paths in the cr2 files). That was my chief reason for purchasing CRPro initially. With careful scrutiny, you'll observe some contradiction in my comments above. If I keep all my millennium textures in my V3 character library, then it is of course going to be necessary for me to have that runtime loaded in Poser when I wish to apply maybe a MAT pose to S3 from her own runtime library. I have no problem with such issues. I can't envisage a time when my V3 runtime is not going to be an essential loaded pre-requisite within Poser for me, and my own decision has been to use this particular runtime library (currently over 5 Gigs) as a convenient repository when encountering the inevitable 'overlaps' you describe. As a related point here, I will add that I personally find little problems with accommodating a characters own clothing items within its own runtime library. Unlike the issue with hair geometries, the object geometries for clothing items are (almost always) specific to the character they are designed for. When there is an overlap, usually with multi-applicable textures, again I'm happy to keep all of my textures in my 'V3 repository'. I hope my (visible) DAZ DRESSED UP (the full title) didn't supply false cues that I advocate keeping clothing separate. That particular library is very much an old WIP (that I'm still gradually re-locating). The one exception here is that - not least because Steve has already taken the trouble to structure things to my liking in zipped downloads - I find it convenient to keep all of the Poserworld stuff in its own self-contained runtime. I tend to keep just about nothing in Poser's native runtime library (apart from the necessary delta files in the !DAZ folder etc). However I have to admit that my own solution for lighting, is to keep all my lighting sets in Poser's own runtime library. Again however, I'm happy to permit duplication here, when maybe I've got a particular lighting sets that is designed specifically for use with a particular item located elsewhere. Also the ANIMALS runtime which is loaded in the screenshot of CRPro is my most recent newly created runtime - normally CRPro would be visibly reporting many thousands of Poser files present. As for re-ordering the listing of runtimes within Poser, the only way is indeed to delete the library references, and then re-add them in your preferred order. This doesn't take long though. ...oh, and I wish you good luck in your endeavours. I think that one day you'll also be very glad to have started a task that time will almost certainly make more difficult - but imperative.
