There's only so much information I can absorb, so I'm calling it a day for tutorials.
Mystical Art Design created a chubby G8F shape for DAZ, "Molly" for G8.1F. I'm going to have a bit of fun with it.
In case you're interested in having your own Molly for DAZ:

You'll need a sharecg.com account to download, btw.
