Problem with 3D lights?

I'm new to Fusion but very excited to have it available for Mac and eager to add it to my tool set. Thanks to you guys for making it available.

I'm not sure if this is a bug or if I'm doing something wrong but I can't get lights to work at all in 3D. Default lighting works fine but it seems like lights I add to my composition... well... they cast no light at all. I've double and triple checked my settings, making sure all of my nodes are connected but I get nothing. If I'm doing something wrong please help. If it's a bug I understand beta's can be that way.

Thanks for any help you can give me.

Any lights? Or just past a certain number?

did you enable "light" in the viewer when you watch your 3d scene?

did you enable lighting for rendering in the render3d node?
