Still messing with Genesis 1... and finding that, except for a couple of adaptations, I have pretty much everything I need.
The mesh is Genesis 1, the skin is G3F iray (except the eyes, which I got from a G2F skin), the costume is all G9(!), and the pose is a converted G8 pose with a G2 hand pose tacked onto the right hand. The scene is a simple HDRI click-in. It really took nothing at all to put it together.
Now, if you don't mind, I have a ton of G3F pose sets I need to batch-run through the ringer (an independent 3rd-party app) to convert for G1 use.
