Up to this point; I am able to import Genesis 9 characters into CC4. I resculpt the eyes as they are always a blank white (an user on the daz forums helped me get this far - https://www.daz3d.com/forums/discussion/comment/7976481#Comment_7976481).

The model looks like it is ready to go but it is only a humanoid model now and seems to not be compatible with a good swath of cc4's features. Is there a way to fully convert my gen9 model to a full CC3+ model? 


Procedure for exporting Daz gen9 character - Import to CC4 response from a very helpful Daz3d member.

"It is certainly possible. Before exporting your Gen 9 figure from Studio, make sure you right click on the Gen 9 figure in the Scene tab and select "All" which makes sure all your bones, clothes, hair goes over into the exported fbx.

Importing the figure into CC4, don't use Transformer, (although I guess there will be an update to correct this in future), instead import your figure as a Human-Non Standard. Close the Characterization tab. Next, open the AccuRIG tab, select Create Guides and click OK. When that finishes, select Generate Skeleton from the AccuRIG menu and let CC4 do its thing. When that finishes, select Bind Skin and let that finish.

Then you can click on Check Animation and select a Motion, to make sure everything is working fine.  

The figure still has the scary white eyes, so come out of AccuRIG and go to Edit Mesh in the CC4 menu. Select Sculpt, then click on the eyeball symbol next to Brush Type. Adjust the Radius of the red circle to be the same size as the eye and click on the eyeballs. You will get the pupils back - WOO HOO!

Then click carefully on any white areas still visible around the eyes, including the surrounding whites and also the "tear" area, adjusting the radius as needed. This is a bit fiddly, but worth spending a bit of time getting this right. You can go out of Edit Mesh mode to check what it looks like, go back in to have another tweak if you need - it might take a few goes to get everything covered. 

 After that, you should be good to go. "
