Custom post processing: Not rendering outside of editor

Unity Engine

Hello Unity Community,

I’m having trouble with scripted post-processing shaders. The shader itself works inside the editor but as soon as I build and run the project I get a black screen. Most probably I’m doing something wrong…

I created a tiny sample that shows the problem. I hope someone can reproduce the problem.

What I’m doing is this: Attach a custom shader to a material and call Graphics.blit(…) during the OnImageRender callback of the main camera. (Is that the way to go?)

I’m using the Unity3d Pro Trial on Win7 64bit. The build itself is 32bit.

Here is the complete code (just in case…)

PostShader.cs

using UnityEngine;
using System.Collections;

public class PostShader : MonoBehaviour {
	
	private Material mat;
	
	// Use this for initialization
	void Start () {
		mat = new Material(Shader.Find("Custom/PostShader"));
	}
	
	// Update is called once per frame
	void Update () {
	
	}
	
	void OnRenderImage (RenderTexture src, RenderTexture dst) {
		Graphics.Blit(src, dst, mat);
	}
}

PostShader.shader

Shader "Custom/PostShader" {
	Properties {
		_MainTex ("Base (RGB)", 2D) = "white" {}
	}
	SubShader {
		Tags { "RenderType"="Opaque" }
		LOD 200
		
		CGPROGRAM
		#pragma surface surf Lambert

		sampler2D _MainTex;

		struct Input {
			float2 uv_MainTex;
		};

		void surf (Input IN, inout SurfaceOutput o) {
			half4 c = tex2D (_MainTex, IN.uv_MainTex);
			o.Albedo = half3(c.b, c.r, c.g);
			o.Alpha = c.a;
		}
		ENDCG
	} 
	FallBack "Diffuse"
}

Any suggestions are appreciated!

Kind Regards,
Gregg

Hi,

IIIRC you have to place your shader in the Assets/Resources folder so it gets included in the build. This is because your shader is being loaded at runtime via script and therefore when the build takes place there is actually nothing referencing it in the scene and therefore Unity doesn’t know it should be included in the build.

Hello Gaski,

yes, that was it! I’d never would have figured this out in time, as I’m a total beginner. Thank you so much!

Best wishes,
Gregg
