Hi, i use Quick Outline from asset store to draw my 3d gameobject outline, it work, but have some problem, when 2 gameobject collapse each other, collapse area don’t draw outline. I want outline draw by Z-order of gameoject, how can i achieve this?
Shader Code:
Shader "Custom/Outline Fill" {
Properties {
[Enum(UnityEngine.Rendering.CompareFunction)] _ZTest("ZTest", Float) = 0
_OutlineColor("Outline Color", Color) = (1, 1, 1, 1)
_OutlineWidth("Outline Width", Range(0, 10)) = 2
}
SubShader {
Tags {
"Queue" = "Transparent+110"
"RenderType" = "Transparent"
"DisableBatching" = "True"
}
Pass {
Name "Fill"
Cull Off
ZTest [_ZTest]
ZWrite Off
Blend SrcAlpha OneMinusSrcAlpha
ColorMask RGB
Stencil {
Ref 1
Comp NotEqual
Pass Replace
}
CGPROGRAM
#include "UnityCG.cginc"
#pragma vertex vert
#pragma fragment frag
struct appdata {
float4 vertex : POSITION;
float3 smoothNormal : TEXCOORD3;
UNITY_VERTEX_INPUT_INSTANCE_ID
};
struct v2f {
float4 position : SV_POSITION;
fixed4 color : COLOR;
UNITY_VERTEX_OUTPUT_STEREO
};
uniform float _OutlineWidth;
uniform fixed4 _OutlineColor;
v2f vert(appdata input) {
v2f output;
UNITY_SETUP_INSTANCE_ID(input);
UNITY_INITIALIZE_VERTEX_OUTPUT_STEREO(output);
float3 viewPosition = UnityObjectToViewPos(input.vertex);
float3 viewNormal = normalize(mul((float3x3)UNITY_MATRIX_IT_MV, input.smoothNormal));
output.position = UnityViewToClipPos(viewPosition + viewNormal * -viewPosition.z * _OutlineWidth / 1000.0);
output.color = _OutlineColor;
return output;
}
fixed4 frag(v2f input) : SV_Target {
return input.color;
}
ENDCG
}
}
}
Normal Outline
When 2 cube collapse
What i want to achieve, outline by Zorder
