UI Blur shader doesn't work in Universal/Lightweight Render Pipeline

[Hertzole]

As the title says, the provided UI blur shader doesn’t work at all when using Universal/Lightweight Render Pipeline. Upgrading materials also does nothing, as expected.

Reproduced

This is because the shader is based on GrabPass which is not supported in SRPs and replaced by CameraOpaqueTexture

[Yusuf Ismail]

_CameraColorTexture will likely be needed for an SRP friendly version

I’ve added an SRP friendly prefab and theme variant in V2.5.1 that uses the default UI shader, so I’ll be closing this for now

If you want to help contribute an SRP friendly version of the blur shader, please get in touch
