This is my outline shader, which i am using, it doesnt seem to work in android after building it.
the shader:
Shader “Hidden/OutlineEffect”
{
Properties
{
_MainTex (“Base (RGB)”, 2D) = “white” {}
_LineColor (“Line Color”, Color) = (1,1,1,.5)
}
SubShader
{
Pass
{
Tags { "RenderType"="Opaque" }
LOD 200
ZTest Always
ZWrite Off
Cull Off
