Here’s a bit of context: [What Happened to CUSTOM\_FRAGMENT\_UPDATE\_ALBEDO](https://forum.babylonjs.com/t/what-happened-to-custom-fragment-update-albedo/10276/6)

I think what you will need to change is in `_createShaderChunks`, after the line `const fragment = Effect.ShadersStore[shaderName + "PixelShader"];` do:

```auto
fragment = fragment.replace(/#include<pbrBlockAlbedoOpacity>/g, Effect.IncludesShadersStore["pbrBlockAlbedoOpacity"]);
fragment = fragment.replace(/#include<pbrBlockReflectivity>/g, Effect.IncludesShadersStore["pbrBlockReflectivity"]);
fragment = fragment.replace(/#include<pbrBlockFinalColorComposition>/g, Effect.IncludesShadersStore["pbrBlockFinalColorComposition"]);

```

Those are the changes that have been made to `PBRCustomMaterial` when the shader code refactoring took place.
