Custom Effect removed from PostProcessingVolume on load

So I have a custom effect, it looks great. I add it to the post processing stack, run around, and admire this great effect. However any time I save Unity, close out, and reopen, my custom effect is removed from the Post processing stack, meaning that every time I load my project, I have to reconfigure this effect. Apparently my code isn't serializing properly, but to me it looks fine.

Code (CSharp):

1. using System;
2. using UnityEngine;
3. using UnityEngine.Rendering.PostProcessing;
4.  
5. [Serializable]
6. [PostProcess(typeof(RetroFxRenderer), PostProcessEvent.AfterStack, "I-Game-Art/RetroFxShader")]
7.  
8. public class RetroFXPost : PostProcessEffectSettings
9. {
10.     [Range(1, 128), Tooltip("Bit Depth Value")]
11.     public IntParameter BitDepth = new IntParameter { value = 16 };
12. }
13.  
14. public class RetroFxRenderer : PostProcessEffectRenderer<RetroFXPost>
15. {
16.     public override void Render(PostProcessRenderContext context)
17.     {
18.         int xScrn = Screen.width, yScrn = Screen.height;
19.         //Texture2D Dith = Resources.Load(settings.DitherTexture) as Texture2D;
20.  
21.         //int xDith = Dith.width, yDith = Dith.height;
22.         var sheet = context.propertySheets.Get(Shader.Find("RetroFxShader"));
23.         sheet.properties.SetFloat("_Bdpth", settings.BitDepth);
24.         context.command.BlitFullscreenTriangle(context.source, context.destination, sheet, 0);
25.     }
26. }

 

Hi did you ever figure out the solution for your problem? I downloaded a PPv2 custom effect asset from the store, and does the same thing. After opening Unity, the effect gets removed from the profile every time.

 

SAME HERE!

 

I've been having this same problem with my custom effects for months. Anyone ever figure out the cause?
