No it's not right. The yellow means close to too much. When you see it on half the light meter, it is to much. A  touch of yellow is OK.

Any orange or red is bad.

And in order to see some 3D, you really want some contrast - light from below should not be near solid white like that. You want the upper part of the disk to have more white than the lower part.

Also, notice the specular ring is black. That means you're using only IBL and getting no specular effects. I wondered about that - it being VSS there should be some nice shine on the skin. But somehow the specular lighting is gone. That's why the skin looks dry.

IBL only affects diffuse lighting in Poser. We use other lights to balance. Sometimes we make an infinite or a spot with less Diffuse_Color in it, perhaps even 0 (black). Such a light (black diffuse) is called a specular-only light.

We have to use IBL for fast global illumination, but used alone it produces that dry look. You want to balance it correctly with specular-only lights. That's why the BBLightMeter is so great. If things are in balance, the ring and the disk will look about the same. If one is white and the other is dark, it is not balanced.

When I submitted those original VSS light sets, I didn't yet have a full grasp of this - that's why they are not so good. I should get my ass in gear and delete those and provide good ones.
