One thing that's still not clear to me is, how to get any of the (custom) V4-Charcters into Genesis.

Straightly asked:

If I look at the right side of this website, I see the "What's Hot Today" ads. In there I see "Betty for V4 .. " by Vyktohria. (Just to use her as an example, for my question).

How would I get "her" (or any other character on that matter) into Genesis in Poser?

Can someone please tell me how this could be done, and what else, beside the installed DSON-Importer, i eventually would need to accomplish this?
