Genesis like V4 and others have multiple maps. The only way to texture properly in Photoshop 5.5. you would have to have a character with one map. 

I would love to know a work round to that issue but haven't found it yet.. My favorite program to texture DAZ characters is Deep Paint 3d, you can texture on multiple layers
and use Photoshop together. They aren't updating Deep Paint 3D any more but still it's worth it for all of DAZ characters.

Hope I've helped...
