After reading previous set of posts I decided to check how a fully clothed DAZ figure imported. I screen-shot all the steps and I might be able to generate a tutorial. As seems to be common experience the textures were automatic but the transparencies weren't. After noting that transmaps looked fine in direct light but lousy in indirect (aka GI) illumination, I made the above test. These are two identical spheres, identically textured, each with a spot light aimed at it. As you can see, Skylight is enabled as is "Light through transparency." The sphere on the right is inside a much larger, fully transparent sphere, with no other material channels and "no light interactions when fully transparent" checked in the materials. Note the result. The spot light shines through the transparency without difficulty. However, the sky light is stopped dead. This may seem like a little issue. But imagine the effect when GI rendering is applied to a Poser figure with transmapped hair, brows, and lashes, and transparent eyeballs. Incidently, with "Visible" unchecked in the assemble room, light does get through...but dimly! C3, Mac OS.
