shave + vrayHairMtl3

For Maya nHair that you can add a vray attribute to the hairSystemShape and connect a Vray Hair Material to it. Much easier than with Shave. Then in the HyperShade you connect the hair Sampler (middle mouse drag) into the various inputs of the Vray Hair Material in the attribute editor. By default it connects the outColor to all of them, which is what I want.
