clear sundial
Anyone know how do change the scale the billboard based off distance from player ie visually it looks the same size no matter the distance im using the BillboardMage shader to create a billboard I even tried making my own shader but it only works in unity not ingame
// Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)'
Shader "Unlit/BillboardTest"

_MainTex ("Texture", 2D) = "white" {}

_ReferenceDistance ("Reference Distance", Float) = 10
