Good day!
I have gotten my hands on a great hair shader, the best i've ever seen so far. Now **I need to change the main color**, but I don't have a clue how this can be done. I googled a lot and tried alot but it seems I'm not capable to get the magic done within this beast of a script.
Shader "Custom/Hair Soft Edge Surface" {
Properties {
_Color ("Main Color", Color) = (1,1,1,1)
_MainTex ("Diffuse (RGB) Alpha (A)", 2D) = "black" {}
_SpecularTex ("Specular (R) Gloss (G) Null (B)", 2D) = "gray" {}
_BumpMap ("Normal (Normal)", 2D) = "bump" {}
_AnisoDirection ("Anisotropic Direction (RGB) Anisotropic Mask (A)", 2D) = "bump" {}
_AnisoOffset ("Anisotropic Highlight Offset", Range(-0.5,0.5)) = -0.2
_Cutoff ("Alpha Cut-Off Threshold", Range(0,1)) = 0.5
_Fresnel ("Fresnel Value", Float) = 0.028
}
SubShader {
Tags { "RenderType" = "TransparentCutout" }

FallBack "Transparent/Cutout/VertexLit"

There is already a variable (Main Color) that should alter the main color in the inspector, but it does nothing at all.
Any advice would be most welcome!
