Custom Post Effects not working on Mobile in LWRP

So I followed tutorial on github about creating custom post effects for stack. made simple test effect wich multiplies screen texture by 2. In editor it works fine, but on android it messes up everything, UI gets duplicated multiple times covering whole screen.

What is wrong? LWRP do not support custom effects?

Code:

Code (CSharp):

1. using System;
2. using UnityEngine;
3. using UnityEngine.Rendering.PostProcessing;
4. using UnityEngine.Rendering;
5.  
6.  
7. [Serializable]
8. [PostProcess(typeof(MyGlowEffectRenderer), PostProcessEvent.AfterStack, "Custom/MyGlowEffect")]
9. public sealed class MyGlowEffect : PostProcessEffectSettings
10. {
11.     [Range(0f, 5f), Tooltip("Glow effect intensity.")]
12.     public FloatParameter gloawStrength = new FloatParameter { value = 1.0f };
13. }
14.  
15. public sealed class MyGlowEffectRenderer : PostProcessEffectRenderer<MyGlowEffect>
16. {
17.     public override void Render(PostProcessRenderContext context)
18.     {
19.         var sheet = context.propertySheets.Get(Shader.Find("Hidden/Custom/MyGlowEffect"));
20.        
21.         context.command.BlitFullscreenTriangle(context.source, context.destination, sheet, 0);
22.     }
23. }

shader pass just samples maintex and outputs it multiplyed by 2.

Here is what I get on my phone


And here is what I see in editor:

 

Did thing get resolved, I'm getting a similar issue in 2019.2.9

 

I thought custom post processing effects do not work in URP anymore?

 

I managed to get it working in the end, it was all to do with the format for how the Image effect shader is written.

Needs to follow this layout

Code (CSharp):

1. Shader "Unlit/SobelFilterBasic"
2. {
3.   Properties
4.       {
5.           .
6.           .
7.     }
8.   HLSLINCLUDE
9.  
10.         #include "Packages/com.unity.postprocessing/PostProcessing/Shaders/StdLib.hlsl"
11.      
12.         .
13.         .
14.         .
15.  
16.     half4 Frag (VaryingsDefault i) : SV_Target
17.     {
18.         .
19.         .
20.  
21.     }
22.  
23.     ENDHLSL
24.  
25.     SubShader
26.     {
27.         Cull Off ZWrite Off ZTest Always
28.  
29.         Pass
30.         {
31.             HLSLPROGRAM
32.                 #pragma vertex VertDefault
33.                 #pragma fragment Frag
34.              
35.             ENDHLSL
36.         }
37.     }
38. }

Without the HLSLINCLUDE it was failing

 

And then that is usable via the PostProcessEffectSettings & PostProcessEffectRenderer as shown above?

And that works with the built in Post processing stack in URP? Or some other way?

Is this for LWRP or URP that you did it on ? Very excited if this is for URP as I have been fighting to find a way to do custom post FX for a while now

 

So this was using LWRP with a custom effect
I was doing a custom outline post effect for the v2 post processing stack.
You just need a shader defined as above and a little bit of C# to link it into the stack as the original post shows

I followed this in the end:
https://docs.unity3d.com/Packages/com.unity.postprocessing@2.1/manual/Writing-Custom-Effects.html

 

Ahh okay, wont work for me then as I need it to work with URP and LWRP is deprecated now anyway.

 

Of course naturally they've completely changed it for the Universal Render Pipeline in 2019.3 so now trying to track down how that is meant to work...

 

Please let me know if you do work it out, been scratching my head on this one for about 2 weeks now

 

URP doesn't support custom post-processing yet but it's being worked on. I saw a branch for it on GitHub a while back.

 

Yup I downloaded the Github files and tried out the samples, I'm going to stick with 2019.2 for now
