I am well aware that DSON products do not work well in DAZ, and I am not surprised that it's even worse with Gen6-- I can't imagine the HD products/options working in Poser, in particular.

 

However, what I said is still true-- V4 is going by the wayside, little by little. 

 

Certainly the majority of new releases on the page today are overwhelmingly V4.
I seem to have overestimated the conversion, based partly on the freebies trend (very little free stuff for V4 anymore-- vast majority is for G2F and both versions of Dawn)

I did look at some of the vendor patterns, however.

 

Vendors who make exclusively for Gen6 or Dawn now: Dariofish, Dzheng, Jroulin, Kang1hyun, Karth, Kobamax, Oskarsson, OutofTouch's clothing, Sickleyield

Vendors who make stuff for V4 OR Gen6 & Dawn: 3DSublimeProductions,  Artemis, FWArt, Halcyone (almost none for V4 anymore), Lilflame, Outoftouch's hair (always compat. w. V4 and Gen6), P3Design, Rhiannon, Sabby

Please note that for clothing and hair, only MODELS, not textures are included. This list is by no means exhaustive, and does not include vendors who usually make products compatible with both or all three figures.
