Fresnel fonction & layer weight node
Posted: Wed Jan 13, 2021 2:11 pm
Hi guys !
Here is the situation : we are trying to create a nice Velvet shader with Luxcore engine but we are stopped by some issues.
__We first try with the original velvet shader in side Luxcore. it was good and have control we need like smoothness of transition between color in the middle and color of the velvet at the tangent. But what we want to fix here for our need is a less saturated tangent color :
__Switching to the disney with the sheen fonction we are able to get a good saturation level at the tangent but we can't tweak the transition curve (sharp or smooth ) between center color and tangent color.
__Finally here is a cycles try but with frenel fonction node : But if we want that in Luxcore i fear the fresnel/facing node can break other stuff in the engine.
So is it possible to add a parameter to desaturate luxcore original velvet tangent color ? or make the color in tangent less saturated with the velvet.
Or a bit harder a i think make possible to affect the sheen transition curve in the disney shader.
