"Reverse" reflection and glossiness values in materials

[blank...]

Considering new PBR workflow "reverse" reflection and glossiness values in materials, reflection to 1 and glossiness to 0.

While i could agree about reflection, but setting glossiness to zero, makes... zero sense to me. I make vastly more materials with glossiness 1 than with glosiness 0. In fact i can't remember if i ever created material with zero glossiness.

So, all that is needed is to split the difference.. Set it to 0.5 :)

But with the new PBR materials you get perfectly shiny polished material with glossiness set to 1, other then a mirror I don't think I ever created such a material.
I was just about to suggest the same thing as Fluss did, maybe not zero but 0.5, nice and reflective but not super polished.

Old or new PBR it doesn't matter, but for glass, liquids, coatings i always use glossiness 1, and in ~80% other cases, my glossiness is mapped, so no, i wouldn't want 0, 0.5 or 0.25. Value of one is perfect for me ;]

as ludvik explained elsewhere (albeit quite harshly), this setup would result in huge slowdown when rendering materials that do not need glossiness. We will wait with bigger conceptual changes for corona PBR shader.
