Best way to have a quad or plane hover just above another objects normal?

Questions & Answers
1

As the title says I am using a texture on a quad that is z-Fighting ‘stitching’ so I have to have it hover above the faces normal.
I tried with .forward but that wont work.

firstObj.transform.position = secondObj.transform.position + (-Vector3.forward * 0.1f)

I know it has something to do with the normal but I cant remember.

Thanks, any help will be appreciated!

You can use this shader which makes the object render slightly towards the camera so you don’t have to manually adjust the transform.position.

Shader "Custom/BlendedDecal"
{
	Properties
	{
		_Color ("Tint", Color) = (1,1,1,1)
		_MainTex ("Texture", 2D) = "white" {}
	}
	
	SubShader
	{
		Lighting Off
		ZTest LEqual
		ZWrite Off
		Tags {"Queue" = "Transparent"}
		Pass
		{
			Alphatest Greater 0
			Blend SrcAlpha OneMinusSrcAlpha
			Offset -1, -1
			SetTexture [_MainTex]
			{
				ConstantColor[_Color]
				Combine texture * constant
			}
		}
	}
}
