How do I write a cutout sprite shader to depth depthtexture ?
Hi!
Tearing my hair out while trying to write only the nontransparent pixels to the depth buffer. I think the issue is that it is using "Legacy Shaders/VertexLit/SHADOWCASTER" for the depth pass but I cannot find a fragment equivalent.
The issue:
My Shader
// Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)'
Shader "Sprites/DefaultWithDepth"
{
Properties
{
[PerRendererData] _MainTex ("Sprite Texture", 2D) = "white" {}
_Color ("Tint", Color) = (1,1,1,1)
[MaterialToggle] PixelSnap ("Pixel snap", Float) = 0
}
SubShader

OUT.texcoord = IN.texcoord;
OUT.color = IN.color * _Color;

OUT.vertex = UnityPixelSnap (OUT.vertex);
#endif
return OUT;
}
sampler2D _MainTex;
fixed4 frag(v2f IN) : SV_Target
{
fixed4 c = tex2D(_MainTex, IN.texcoord) * IN.color;
c.rgb *= c.a;
clip(c.a - 0.5);
return c;
