Sky dome takes out all light on FiberFX?

[Hieron]

Been trying to put a nice skydome all around me fine field of grass. But as soon as I put anything in, all rendered grass becomes pure black.

Anyone have a clue what I am doing wrong? The poly's underneath get light just fine. I tried turning on radiosity for the fun of it.. still black. Other lights, black.. turning shadow options off for the dome, same thing.

Am I missing something here?

Seems like only distant light sources give that issue of black grass.

Still, radiosity doesn't seem to work.. correct? (with tab turned on)
