It's a hard question to answer. That's for sure.

Currently - Smith Micro are hiring a new Poser software team as they moved their Graphics department to a new location - due to this we have to assume that there won't be a new Poser any time soon - and with a new software team we won't know what direction Smith Micro will take Poser in.

Will Daz3D and Smith Micro cooperate and make Daz figures compatible with Poser again..?

Daz3D decided to stop making the Genesis figures compatible with Poser. You can still use Genesis 1 and 2 in Poser with the DSON Plug in if you wish to.

It would be up to Daz3D if they wanted to make a new figure that is compatible with Poser - but as they make their own software I don't think they would feel the need.

If enough Poser customers asked them for a new Poser figure - and I mean many thousands - they might consider it but I doubt it.

V4 and M4 are 10 year old figures now, so it's quite surprising they still have support from the community.

I don't have an answer for you to be honest. - I've also struggled with this conundrum and have considered moving entirely to Daz Studio - but I love Poser more lol

You could try one of the newer Poser figures - Umm - or not lol.  There are supposed to be some new ones eventually ?

You could learn and use Daz Studio as well as Poser.

You could keep using V4 and M4.

You could make cakes and watch tv.
