Whilst I have only used Daz experimentally...
One issue I ran into first time around was that I ended up feeling like I'd completely screwed up my library of assets/content because some of the packages I downloaded couldn't be installed using the Daz Install Manager (DIM).
Instead I unpacked packages directly into my library folders from ZIP/RAR files.
Whilst stuff worked, I soon reached a point where there were assets I didn't want anymore - except I couldn't really separate out the individual files to get rid of them.
By the time I'd faffed about a bit, I was getting errors and stuff and so ended up deleting everything so that I could start from a blank slate again - because I didn't trust the database of assets actually matched the assets I had any more.
I promised myself I wouldn't install anything in the future that couldn't be installed via DIM (Or I would at least figure out
the thread that lets you set up the DIM metadata for packages that didn't have them). Instead I just abandoned the idea of using Daz - because it was easier, I'm a slacker and I didn't have a project in mind.
I offer this only as a cautionary tales of putting everything in just one single place.
If I were to every try Daz again the future, I think I would probably have at least 3 libraries defined to Daz (as Rich described earlier).
- The default Daz library stored in C:\{wherever}\
- A second Daz library on my D:\dev\Daz\DIM Library\
- A third Daz library, probably under D:\dev\Daz\Other Sources\
My second library is primarily because my D:\dev\ folder tends to be where I keep all my development source files and because my D: drive is a RAID array for extra redundancy. I would probably even go so far as to make this my default installation library for DIM.
My third library is for my "other" assets not installed properly through DIM and is a reaction to the problems I had the first time around. (It may cause more problems in another way... I dunno). Though it sounds like Renderocity files might be suited to go there... though even then, I might just end up with a fourth library to separate out legit and non-legit packages.
But as I say, all this is theoretical on my part - because I wimped out trying again.
Maybe some seasoned Daz people could highlight any pros and cons for you - just so you could at least consider multiple libraries again rather than a single monolithic one.
