Having spent six months working out the best ways to get the g figures into Poser, I would say it is the underwear answer -

It Depends.......

I use the g1 figure for DarioFish's Aliens, and I use the g1 & g2 children figures (In my comics, my characters have families).

Yes, g figures can be converted from native DS to native Poser figures - which is necessary to avoid the memory issues with DSON.

No, it isn't hard - there are simply a lot of steps that have to be done for every single product you are attempting to bring into Poser.

Is it worth the effort? I would say no - and let me explain WHY, because this is the important part. If you want to get the most use out of g figures in Poser, you need to understand some thing going in.

1. The G figures are quite a bit more expensive than non-DAZ figures. The "Iconic Shapes" are a waste of money - You would be paying an extra $44.95 to use them, and most of those figures only have five or six characters made for them, so you better really, really like them. They also have slightly different UV maps, so you will need to do a bit of extra work in DS to share those skins with your other g2 figures in Poser. Most of the g2 iconic shapes aren't making it to the g3 lifecycle, so I would say that DAZ and vendors have judged them a failure. No more Davids, Stephanies, children of any type, much less any of the newer "iconic shapes"

2. You will spend a great deal of time unscrewing the Poser Companion File folders. As an example, I have 988 packages of g1 & 2 content installed in my ! DIM Default runtime. Out of those 988 packages, NOT ONE has all of the PCFs in the correct subfolders. Think about that for a minute. And speaking of those PCFs, if it only takes me 30 seconds to convert a PCF into a Poser-native file, it begs the question as to why g vendors can't do this (although to be fair, one of them DOES make native PCFs).

3. You are also going to need a thorough understanding of the mess that is the DS file system - unless you don't mind dealing with base figures that take 400Mb of ram - as opposed to setting the same figure up to only need 80Mb of ram. Or if you don't mind your child characters having every gens morph and boob morph that your adult figures have.

4. There are a limited amount of characters - It amuses me to no end to point out that the SM G2 line (Simon, Sydney, etc) had more characters created for them than DAZ managed for either of the first 2 g figures life-cycle. (I counted).

5. A fair portion of the g characters are simply rehashes of gen4 characters. It is the same with clothing - some clothing goes all the way back to P6 Jessi/Victoria 3 timeframe. A good example of this is Mech Girl for g3 - I have the A3 version. Or some of dx30's shoes. I give shoes a pass - due to rigging, you pretty much do have to buy new shoes for each figure.

6. Most of the new clothing being made for the g figures are simply not well made - they lack functionality (movement morphs) that Poser users took for granted back in the gen3 timeframe. IMO, high texture jpgs do not compensate for suit jackets that doesn't button (actually modeled as an open, unbuttoned jacket), pants, skirts, and dresses that lack sitting morphs, etc. OTOH, it is child's play to use dynamic clothing with a g figure (just like any other figure). With a bit of patience, you can use the fitting room with g figures also - although I prefer using the cloth room.

With the g figures, DAZ is actually moving backwards to how things were back during the gen3 lifecycle. I don't view that as progress. I am sure vendors like it - they can retrofit clothing they have modeled for legacy figures & turn around and sell it again at a much higher price (Mech girl example MSRP - A3 version $9.95 - g3 version - $19.95). Much easier than making new content from scratch.

Bottom line - if you want to use g figures in Poser, you are going to have to learn the ins and outs of both programs. No more Load, Conform, Make Art for you.
