I’m not sure, I would expect that the light vector would mirror the widget, so if the arrow is pointing down X, I would expect it to be 1,0,0. But there’s a lot of interpretation too, is it the light reflecting back from the object or is the light coming from the light source, so I guess you could justify it either way.
I’d be happy to fix/clean up my fx and unity shader files and send them over to him. I won’t have access to my computer til maybe end of the weekend, though.
If I ever have money… I’m buying it
