"Queue"="Transparent" not working (on iOS).

I have this simple shader here…

`Shader "MyShaders/Overlay" {
	Properties {
		_Color ("Main Color", Color) = (1,1,1,1)
		_MainTex ("Texture", 2D) = "white" {}
	}
	
	Category {
		Tags {"Queue"="Overlay" "RenderType"="Transparent"}
		ZWrite Off
		Alphatest Greater 0
		Blend SrcAlpha OneMinusSrcAlpha 
		SubShader {
			Material {
				Diffuse [_Color]
				Ambient [_Color]
			}
			Pass {
				Cull Back
				ColorMaterial AmbientAndDiffuse
				Lighting Off
	        	SetTexture [_MainTex] {
	            	Combine texture * primary, texture * primary
	       		}
	        	SetTexture [_MainTex] {
	           		constantColor [_Color]
	            	Combine previous * constant, previous * constant
	       		}  
			}
		} 
	}
}

`

…wich doesn’t work as supposed to do.
I need it to render above everything in the scene, (and it should do it, since “Queue” is set up to “Overlay”), but I’ve the feeling that it’s completely ignoring the “Queue” tag. No matter how I change it, it always renders like its queue is “Transparent”.
Other objects in the scene are all rendered in Geometry and Transparent queue, and their depth sorting is perfect. This is the only one not working.

Any suggestions? Did I write something wrong? Thanks!

Use

ZTest Always

Simple shader question...

Hello, I was wondering if there is any way to edit a shader to always render on top of everything in the scene? Similar to the Text shader. Thanks a lot!! BTW Right now I am trying to get the default additive shader to work. Shader...

The “Queue” specifies the order of the rendering (but the rendering may still be skipped by the zbuffer test). Changing the render-queue is needed for performance tuning and making sure that transparent objects are rendered last (since they should never be overdrawn by an opaque object).
