I need to be able to use this code but without the Cutout part. The shader Transparent/Diffuse works fine for what I am trying to achieve but I want the tranparent/diffuse to be 2 sided like this shader. We are trying to use this shader for Hair which at the base looks really bad since it does that alpha cutoff. This shader is fine for plants but not for hair.
Also wondering if anyone has any advice or would like to share any code they have done or experienced to come out with good looking hair in Unity? Thanks.
Shader “Transparent/Cutout/Diffuse Two Sided” {
Properties {
_Color (“Main Color”, Color) = (1,1,1,1)
_MainTex (“Base (RGB) Trans (A)”, 2D) = “white” {}
_Cutoff (“Alpha cutoff”, Range(0,1)) = 0.5
}
Category {
Cull Off
Alphatest Greater [_Cutoff]
AlphaToMask True
