Shader turns black on iOS build.

Unity Engine

Hi there,
I’m having a bit of an issue where one of my shaders seems to turn out black when i build it to the device.
Any ideas as to what might be causing this? Here’s the shader.

Shader "Pete/Solid Transparent Color" {
Properties {
	_Color ("Solid Color (A = Opacity)", Color) = (0,0,0,1)	
}

Subshader {
	Tags {Queue = Transparent}
	ZWrite on
	Blend SrcAlpha OneMinusSrcAlpha 
	
	Color [_Color]	
	Pass {}
	}
}

Thanks
Pete

Shouldn’t most of the commands be inside the Pass structure? I.e.:

Shader "Pete/Solid Transparent Color" {
Properties {
	_Color ("Solid Color (A = Opacity)", Color) = (0,0,0,1)	
}

Subshader {
	Tags {Queue = Transparent}
	
	Pass {
		ZWrite on
		Blend SrcAlpha OneMinusSrcAlpha 

		Color [_Color]	
	}	
}
}

Hey Thanks Martin,

That does look pretty wrong now that I look at it :slight_smile: , I changed though it and it still appears black in the build.
I’m now thinking it might be something to do with the trail render it is applied to.
