There is a tutorial using Vray up on youtube of how this can work using Vrays hair shader,  i was wondering if in the absence of the old aiHair material if there is a way to do this out of the box possibly using the maya Hair Physical shader.  the issue im encountering has a workaround described here  but that is the old aiHair the new one does not have the UV override option.  Any assistance is much appriciated.
