Hi all,
I recently started using Blender and I like it

and now....When I render a model with the internal blender renderer the model comes out perfect, but when I render this same model (without any changes) with yafray the model is all distorted and dark.Then i add some more light (which is too much for the internal blender renderer) and the yafray rendered model is lit up farely well, but still distorted.What am I doing wrong.....please help....
Try increse "GI power". That can halp a lot.
