Thanks Micheal for the quick feedback on this!
Yes unfortunately i have tried the w coordinates but it gives me a strange result as well, it also changes the coloration to an entirely different tone and washes it out. yes the channel options seemed unstable and were crashing vray as well.
However i will stick to using the vray info tex for now, unfortunately i will have to manually create a multilayer shader setup for it to be able to tweak the hue on such a level to get identical control and result, it will be great to have Oxhair or a similar map fully supported by vray in the future : ) thanks again!
