I think genesis is being used by many right now because they've made ds pro free for the last month (and are doing it for the next month as well.) Actually, they have 3 of thier top of the line software products for free.. grab em.

That said, genesis does not work easily in poser, so most of the poser users aren't even bothering with genesis, and the only store really supporting genesis is daz.

Daz has been talking about a DS plugin to export genesis to poser, But in 3 months we haven't seen any movement there at all, and SM has no plans I've heard of to make genesis compatible with poser at all.

Genesis is pretty nifty, but is also poly light compared with the gen 4 crowd.

A free weight map rigged version of V4 was released a month or so over at RDNA.. grab her as well.

Also, Antonia was released free and also weight mapped, and is an excellent free figure, and can be redistributed for free or commercial use.

Way too many people take way too many things way too seriously.
