I realise that this is a reply to a post you left 7 years ago but it might be very helpful to me now!
I am trying to do exactly what you seemed to have done which is to make 3 sliders to control the HSV adjustment. However I don't understand how you did it and can't figure it out from the image you posted (http://simplymaya.com/forum/attachme...2&d=1087997570
). I was wondering if you could explain how you did it please? Maybe you have the file still or can remember what the connections are or the logic? Anything really would be a massive help!
