Figure--> Skinning Method-->Poser Unimesh...then adjust Subdivision ion the Properties tab of the figure to 1. Render. It may come out all black. If it does, you can either:

1. Use EZSkin in Poser 11, save the adjusted figure materials to your library and render in Poser 12
2. If you have SkinEdit for Poser 12, use that to convert the skin.
3. If you understand nodes, you can manually futz in the Material Room to fix proper Superfly shaders onto your figure. There are several threads on the Poser 12 forum that deal with this.
