Higher glossiness at grazing angle

[dubcat]

My long time wet dream became a reality the other day, but in the wrong render engine :(
Those who have seen my guides, may have noticed that I apply a falloff in the Glossiness chain. This is to simulate that even rough surfaces are glossy on the edges/tangent.

fstorm got this feature the other day "angle affect" increases material glossy for low(tangent) angles"

Could we pleeeeeeease get this feature in Corona ? :)

Here are some examples of "angle affect" 0 - 1.
They are separate images, so you can compare them in a new tab or something.

Yes, nice, this is a really handy feature.

THEA Render has it since a couple of years ago, it´s called Micro Roughness, and it has 2 values to control that effect, something like the radius and the height of those "micro-bumps". A bit too complex for my taste, I would go for a simple 0-1 param like in your example.

AFAIK this is part of disney BRDF model, so it will be almost certainly included in Corona PBR mtl

As this is common to all materials, couldn't this be included in the 'standard' material as well?

This is more or less solved by PBR material
