Helllo all,

I am currently trying my second attempt at making my own shader (the first went badly), so I apoligise in advance if this is relitivly easy as I have little knowlage on shaders. My current goal is to make a Layer Mask.

I am currently coming across a error code as follows:

Shader error in ‘Custom/culling’: Parse error: syntax error at line 11

Code as follows:

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

the most obvious thing to me is a missing closing brace on line 16

Shader compilers sometimes give really unhelpful errors, sometimes with completely wrong line numbers. And there are no completion pop-ups, so easy to misspell a word. I’ve found that you always start with working code, and change only a little at a time before testing.

But, in this case, the error IS on line 11, like it says. This man page has what you need to fix it: Unity - Manual: ShaderLab command: Blend

I ran into the same problem earlier and it proved out to be a typo in there: “ScrAlpha” instead of “SrcAlpha”. Took me a while to figure it out, and I hope it will save others some time.
