Blender Internal Works, Yafray makes "Alpha"

Spent a day searching the Forum, but haven’t found what I need (learned a few other things, though!)

Not sure how to describe the result…but Blender’s renderer works fine. When I try to render using YAFRAY, I basically get Black and White - White where there is any light, Black everywhere else. It looks like an alpha channel. Simple material, just reflective.

I know there is a simple solution here, but obviously I’m pushing the wrong buttons.

Thanks,

the best way to describe is to post the image
