I’m new to shader development. Picked this shader from LeanTouch (Lean Touch | Input Management | Unity Asset Store).
Want to Add GPU Instancing in this anybody can help i would be thankful to him/her.
Shader "Lean/Common/Object"
{
Properties
{
_MainTex("Main Tex", 2D) = "white" {}
_Color("Color", Color) = (1.0, 1.0, 1.0, 1.0)
_Color1("Color 1", Color) = (1.0, 0.5, 0.5, 1.0)
_Color2("Color 2", Color) = (0.5, 0.5, 1.0, 1.0)
_Rim("Rim", Float) = 1.0
_Shift("Shift", Float) = 1.0
}
