Ah, so not lit. The black glass can be due to:

[_] An invalid node connection or parameter value, resulting in that value returning as 0/black.

[_] No backdrop (skydome, etc) for reflections to "see", so you get nothing/black.

[_] Insufficient number of transparency bounces and/or transmission bounces (for refractive glass), resulting in an incomplete raytrace.

Bump up the max bounces as shown in orange. 16 is Superfly's max. That does not mean that Superfly will run sixteen bounces; Superfly will only run as many bounces as it needs in order to complete a raytrace.

Try those fixes. If you still see black, you may to use a different glass shader, depending on whether the glass has thickness or is single-poly, and how thick the glass is.

edit due to crosspost: I keep seeing people give advice that "all you need to do is jack up the ambient/emission". No. Doesn't work. There is considerable discrepancy between the object's apparent brightness and how much light it casts. I can do a lit bulb, but at the moment all of my machines are doing a test animation (with just such mesh lights) for Arrow1's floatplane project. I'll need to build a lightbulb. I can use the modeler (Silo) while Poser/Queue are tied up.

Poser 12, in feet.
