Lighting support in Unlit shader
Hello World! I'm trying to turn on lighting in this unlit shader, actually I tried to convert it to a surface shader but I don't really know what to do, I'll be thankful if somebody helps me :)
Shader "Unlit/RadialGradient"
{
Properties
{
_MainTex ("Texture", 2D) = "white" {}
_NoiseTex("Noise Texture", 2D) = "white" {}
_NoiseForce("Noise Force", Range(0, 500)) = 10
_NoiseScale("Noise Scale", Vector) = (10, 10, 0, 0)
_ColorFrom ("Color From", Color) = (1, 0, 1, 1)
_ColorTo ("Color To", Color) = (1, 1, 0, 1)
_RadiusMultiplier ("Radius", Range(0, 5)) = 1
_GradientPivot ("Position", Vector) = (0, 0, 0, 0)
}
