I try to use YafRay and the output is a mess.
First i created new material and i use my avatar picture for texture (default settings).

What i need to set to see the background in YafRay ?
Thank you !

Not all of Blender’s functions are available to Yafray. Unfortunately World background gradients are one of the unavailable functions. You could use a background plane, or try Yaf(a)ray, it has a nice Sunsky background with Global Illumination.
