Default sampler info node

Hi,

I was just looking at shaders and messing around with them and I noticed that almost EVERY shading network has a sampler node's facing ratio connected to some ramp's v-coord.
Why is that so?
I understand that facing ratio is the angle between the surface normal and the view direction, but why v-coord? why not u-coord?

probably because most of those ramps are v-coord ramps. If you used a u coord ramp you would have to change it I guess.

PS there is more to a samplerInfo than just the facingRatio
