Actually what I said above isn't true. IBL lights do not appear to be working in Superfly anymore with the latest building.

I didn't realize that Poser was switching me to Firefly when I got the results stated above. Doesn't matter whether I set up the IBL myself or use the prompts presented when I add the IBL all I get in superfly is a silhouette. It used to work in superfly, didn't it? That's what I always use.
