Version: Unity 2022.3.8
Using 2D URP
My shader graph works in editor and macOS build, but shows nothing in WebGL build.
In the brower console, it shows:
ERROR: Shader
Output.framework.js.gz:10 Hidden/Universal Render Pipeline/Edge Adaptive Spatial Upsampling shader is not supported on this GPU (none of subshaders/fallbacks are suitable)
Output.framework.js.gz:10 Hidden/Universal/HDRDebugView shader is not supported on this GPU (none of subshaders/fallbacks are suitable)
I figured it out myself. It was due to some of the property reference names starting with two underlines, like “__1”.
so hang on, I am getting the exact same messages about lack of support for those shaders when I do not even use them as far as I know. So where does it come from?
I think URP is including them for some reason and it is not shader graph related
I have the same issue. Any news about that?
Can you report this using the Bug Report tool and providing as much details (Unity version, OS and browser used)?
Thanks
Literally happens on a clean URP template project in 2022 LTS which also spams the audiocontext warning constantly in the browser developer console 
bug IN-77945
This is because those shaders are included in URP builds and require shader target 4.5 (incompatible with webgl 2)
