Hm. I like Nova quite a bit. If you find you use IK a lot you might have trouble with Nova, and I'm assuming Neo. Neither have IK.

Nova is a Genesis 8 derivative. Poserized. It's no big secret. Simply looking at the UVs and Topology, which is virtually identical to G8, is plain to see. The UVs are slightly differently arranged on their respective tiles, I'm assuming so that G8 textures are rendered incompatible. There's other very insignificant differences.

I like Vyuser's figures. I purchased a couple of her DS only figures from Daz. Same deal with them but they work better in DS than Nova (and I assume Neo) do in Poser. The IK thing is a hard pill to swallow. The figures bend very well and have interesting rigging atypical of Poser figures. V4 poses don't translate well, G8 Poses do with some tweaking and a means to convert them. Nova has additional leg and arm bones, and very flexible abdomen and neck, multi boned. I assume Neo is set up virtually the same way. The face is also rigged with numerous bones but aren't integrated well and are a bit tricky or clunky to use. There's some weightmapping issues with the conforming lashes, easily fixed. Also many of the crosstalk morphs with the facial conformers are poorly implemented. I also fixed that.

I had a whole thread dedicated to Nova here...

There's some rather elaborate morph packs that I made. Some fixes to her conforming lashes and crosstalk stuff. Some hair fits. I kind of drifted away from it because her lack of IK became annoying. It's not possible, that I know of, to manually set up an IK hierarchy with the state of her rigging and it's divergence from some Poser standards.
