I think it’s not impossible, but you need workaround’s. The last Genesis figure that works well in Poser was Genesis 2 (male and female). The newer figures don’t work well in Poser.

So if you prefer Poser 11 or 12 you should consider the Poser native figures or V4 / M4 from DAZ.

V4 and M4 are still available with Poser installer.

Genesis 3, 8 and 9 work well with all the possibilities in the native program that is for free  with a big “But” !!!  -you need a few add on to make the program work like Poser. At last, it is a decision which figures you like more and which program you prefer.
