I have been meaning to get around to doing some Yafray renders to test it out and see what it can do. I finally got around to doing it, and I have to say I like it a lot. I wanted to test out HDRI lighting as well.
The scene below has no lamps at all; all the lighting is HDRI. The render is a pen, with a magnatized base, (the little chrome donut shaped object) that hold the pen upright when it is placed on the base. The red cubes I just threw in to test caustics and add variation. I hope you like it.
This is my first Yafray render, so if you have any crits on how to improve, I am all ears.
