I see.....XYZ are encoded in the RGB and albedo in the alpha chanel if it exists. How ingenious.

I also just noticed (I am reading Wikipedia) that the Nvidia cards have normal rendering implemented in hardware. They are speaking about gamer cards right there, but hopefully it is also implemented in Nvidia's DCC cards: I just bought a Quadro FX 570. It is sitting on a box on my table awaiting installation tomorrow.
