Hey,
i searching for whiles now for an outline shader working with hdrp…
to be honest i have realy no knowledge with shader programing, and are very happy with the new shadergraph.
i just read some Topics about Outline Shader and i think i got some Idea how it should work. This is my “simple” definition what i understand. Scale the Vertex of an object from actual view angle to get the Outline.
In the Shadergraph i just found Vertex Color. i guess it is not implemented yet into the Graph.
Then i looked into this Asset:
i Think it got all what i need but i guess the shader isnt compatible with the HDRP Pipeline here is the Code from the Fill and Mask Shader (due it is free i hope it is no problem to post it here):

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"

ZTest [_ZTest]
ZWrite Off
Blend SrcAlpha OneMinusSrcAlpha
ColorMask RGB
Stencil {

Comp NotEqual
}
CGPROGRAM
#include "UnityCG.cginc"
#pragma vertex vert
#pragma fragment frag
struct appdata {
float4 vertex : POSITION;
float3 normal : NORMAL;
float3 smoothNormal : TEXCOORD3;
UNITY_VERTEX_INPUT_INSTANCE_ID
};
struct v2f {
float4 position : SV_POSITION;
fixed4 color : COLOR;
UNITY_VERTEX_OUTPUT_STEREO
};
uniform fixed4 _OutlineColor;
uniform float _OutlineWidth;
v2f vert(appdata input) {
v2f output;
UNITY_SETUP_INSTANCE_ID(input);
UNITY_INITIALIZE_VERTEX_OUTPUT_STEREO(output);
float3 normal = any(input.smoothNormal) ? input.smoothNormal : input.normal;
float3 viewPosition = UnityObjectToViewPos(input.vertex);
float3 viewNormal = normalize(mul((float3x3)UNITY_MATRIX_IT_MV, normal));
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
}
}
}
And the Mask Shader:
//
// OutlineMask.shader
// QuickOutline
//

//
Shader "Custom/Outline Mask" {
Properties {
[Enum(UnityEngine.Rendering.CompareFunction)] _ZTest("ZTest", Float) = 0
}
SubShader {
Tags {
"Queue" = "Transparent+100"
"RenderType" = "Transparent"
}
Pass {
Name "Mask"
Cull Off
ZTest [_ZTest]
ZWrite Off
ColorMask 0
Stencil {
Ref 1
Pass Replace
}
}
}
}
Is there any way to get this two shaders working within the new pipeline (changing wording or implementing the right library) Does anybody have an Idea ?
Or is there some way to get the vertex “displacement” into the Shader Graph Custom Node ?
