AdditiveTint projector doesn't display anything
Hello,
for my test RTS project I'm currently working at the unit selection. But I'm struggeling with the projector. I have added a new Projector:
Shader "Projector/AdditiveTint" {
Properties {
_Color ("Tint Color", Color) = (1,1,1,1)
_Attenuation ("Falloff", Range(0.0, 1.0)) = 1.0
_ShadowTex ("Cookie", 2D) = "gray" {}
}
Subshader {
Tags {"Queue"="Transparent"}
Pass {
ZWrite Off
ColorMask RGB
Blend SrcAlpha One // Additive blending
Offset -1, -1
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#include "UnityCG.cginc"
struct v2f {
float4 uvShadow : TEXCOORD0;
float4 pos : SV_POSITION;
};
float4x4 _Projector;
float4x4 _ProjectorClip;
v2f vert (float4 vertex : POSITION)
{
v2f o;
o.pos = mul (UNITY_MATRIX_MVP, vertex);
o.uvShadow = mul (_Projector, vertex);
return o;
}
sampler2D _ShadowTex;
fixed4 _Color;
float _Attenuation;
fixed4 frag (v2f i) : SV_Target
{
// Apply alpha mask
fixed4 texCookie = tex2Dproj (_ShadowTex, UNITY_PROJ_COORD(i.uvShadow));
fixed4 outColor = _Color * texCookie.a;
// Attenuation
float depth = i.uvShadow.z; // [-1 (near), 1 (far)]
return outColor * clamp(1.0 - abs(depth) + _Attenuation, 0.0, 1.0);
}
ENDCG
}
}
}
I have a Material with the circle, a cookie with type spotlight and this cokkie as default map for the projector.
