simple outline shader, using the vertex normal
Beneath is a method of drawing outlines around our mesh - or rather, we're expanding the mesh, giving it a flat colour and then drawing the mesh as normal on top of it. Note that we have two CGPROGRAM blocks, which get executed in order. This type of outline requires the transparent tag to work properly, and this could cause problems elsewhere.. Also it only outlines the extremities of a shape - or you could say, just the alpha edges . Next post will feature a more advanced shader Shader "Dave/Unlit/simpleOutline" { Properties { _MainTex("Texture",2D) = "white"{} _OutlineColor("Outline Colour",color)=(0,0,0,1) _Outline("Outline Width",Range(-0.1,0.1))=0.005 } SubShader{ Tags{"Queue"="Transparent"} ZWrite off ...
