yafray renders are black

I am currently reading the book Digital Lighting and Rendering by Jeremy Birn. In the book there are some lighting methods discussed that the Blender Internal Renderer is incapable of(caustics, GI, etc.)

So I figured I would use Yafray instead. However, when I try to render something, the screen is black. I am sure that I have Yafray installed. Any advice or suggestions are welcome.


If you are using Blender 2.46 make sure you select the XML button in the Yafray Render settings. Also, turn on Yafray’s GI just to make sure you have enough light in your scene.

Thank you, I have gotten it to work(now if I can just learn to use it…).
