Minimap camera transparency

Hello.

I followed this tutorial on how to make a minimap using a camera that’s pointing to the terrain:

What I’m trying to figure out right now though, is how to make my map a little transparent.

The tutorial gives me a shader to use on my material, otherwise i’d just use a transparent one and go with that… but now that I have this shader, how do I make it so the map is transparent?

Shader code:

Shader "Custom/Mask"
{
	Properties
	{
		_MainTex ("Main Texture", 2D) = "white" {}
		_Mask ("Mask Texture", 2D) = "white" {}
	}
	
	SubShader
	{
		Tags { "Queue"="Transparent" }
		Lighting On
		ZWrite Off
		Blend SrcAlpha OneMinusSrcAlpha
		
		Pass
		{
			SetTexture [_Mask] {combine texture}
			SetTexture [_MainTex] {combine texture, previous}
		}
	}
	
}

Meanwhile I’m trying to figure out shaders… thanks.

Hi,
You can use the KGFMapSystem in combination with a 50% alpha mask.

The KGFMapSystem comes with a lot of useful minimap/map features is well documented and tested on pc, osx, android, ios and web.
