Quote - would that be best done in a new scene with just a naked Lilo and the hair?  

Nope. Just the hair is needed, no need to save the figure or anything else from the scene.

Quote - "Can anyone point me to a really good detailed tutorial on how to build multiple runtimes (geared for newbies lol* or maybe there should be a "Poser for Dummies" book )"

It's really pretty easy.  The problem is that most people over think it.  

Just remember that an external runtime is exactly the same as the runtime in your Poser folder, only it's just sitting in a different location.  

It functions exactly the same way. 

And files are installed / added to them in exactly the same way. 

And they have the same folders in them as the main runtime does. Well almost the same folders.  Scripts for example have to be installed into the main Poser runtime and won't work from an external runtime.

Here is a sample of an external runtime.  Simply download it and unzip it. You will have a folder called "Runtime_Sample"

Find a place on your hard drive that you want to have your external runtimes living. For me it's on my partitioned drive D.

Make a folder called "Poser Runtimes"

Then simply copy that sample runtime you unzipped into that "Poser Runtimes" folder and make as many copies of it as you want to.  Change "Runtime_Sample" to whatever name you want.  Here is what I named some of mine:

Then all you do is simply install your content into whichever runtime you feel it fits best into.

Once you have finished installing your content look in the Runtimes where you have Daz characters such as V3 or V4 etc.  Go into the Library folder and look for the !DAZ folder.  Make a COPY of that folder and place the COPY in exactly the same place in the main Poser Runtime. 

Poser looks there first so by placing a copy of them in there, you are helping Poser out.  Don't delete the !DAZ folder from your other runtimes though. That defeats the purpose of having external runtimes, which is not only to allow Poser to work faster, organize your content better, but also to not lose your installed runtime content in the even of a crash because hopefully you have also saved your external runtimes to a couple other places for easy access in case of the need to reinstall.

Hope that helps.  If you have more questions, just ask.

Oh yeah, never install anything directly to your runtime. Always unzip / install to a folder on your desk top so you can see what is in side and what the folder structure is.
