Shader cache is not automatically updated for packages copied into /Packages folder

Posted there: https://forum.unity.com/threads/fee...-render-pipelines.470095/page-18#post-3605390, but to make it more obvious, I post it again.

For customization of officially provided SRP packages like LWRP/HDRP, we copy the package into <project>/Packages/, so it can be managed together with the project via VCS. However, modifying shaders do not automatically update the project's shader cache. I guess there's something to do on the C++ side of the engine.

 

https://docs.unity3d.com/2018.3/Documentation/Manual/ScriptableRenderPipeline.html
The document says there should be a /ScriptableRenderPipeline folder side-by-side to /Assets, and the *.json file in /Packages refers to packages in /ScriptableRenderPipeline.

Does this setup make shader cache work? What setup is used to make shader cache work when developing SRP internally?

 

See fixed on 2018.3.0b2.
