Here's how to run a Gen figure in poser without the DSON plugin. Now you will need DS installed but just long enough to export what you need...

In DS load your figure and add all the morphs you're going to use.

File > Export ... Choose CR2 as the format

Save it into a library mapped to Poser

You'll need to make sure all your textures are in that library too.

Open Poser and load the exported figure from Poser's library.

OK now for the bad news. There are several serious issues with this figure. First the scaling is totally hosed. Studio does not export any scaling information. You didn't lose anything over DSON cuz DSON doesn't get it right either. If you need to apply materials you will have to do that manually. Once again you haven't lost a lot because the conversion is only marginal at best. And if you're going to render in Octane you'll probably need to rework the materials any way.

Hope this helps.

P.S. Shameless plug for Dawn goes here.

DO NOT use this method to export genesis figures. This method predates the DSON importer and is the the reason the DSON importer was created. If you follow Joepublics instructions to load the figure with the importer you will get a much better functioning figure and you're able to apply materials from material files (to the UV that you exported that is)  and properly use scaling. Only thing that doesn't work is HD morphs due to the implementation of the Pixar subdivision. Nerd, you gotta do your research on this subject if you're going to do your job properly because you're like two years behind on the importer and a year on Joepublic's method.

EDIT: If you're trying to do cross platform development for Dawn then you could use the exporter to get a cr2 to fix in Poser and adjust the weight maps.
