// Note : Also requires setting up "_TessellationUniform" Float in Blackboard

/*
Allows you to inject tessellation into SG & URP, but hacky / can be difficult to work with.

While this works, it's maybe not as useful as you might think. I believe any vertex displacement would need to be 
taken out of the graph and moved into the domain function below (since tessellation still runs after vertex shader).
I thought about using the VertexDescriptionFunction from the generated code, but sadly that's generated after the injection point
so can't be called as it's undeclared at that point.

// Requires a specific shader to read the _PerInstanceData buffer at SV_InstanceID
// I use a shader made in Shader Graph, See : https://gist.github.com/Cyanilux/4046e7bf3725b8f64761bf6cf54a16eb
// Also note, there's no frustum culling involved in this example. Typically a compute shader is used for this.

Copies the camera buffer after rendering opaques, to _CameraOpaqueTexture property so the Scene Color node can work in the Built-in RP.
Attach this script to the Main Camera (and any other cameras you want an Opaque Texture for)
Will also work for Scene Views (Though if a new window is opened will need to enter & exit play mode)
Tested in 2022.2

- Renders DepthOnly pass to _CameraDepthTexture, filtered by LayerMask
- If the depth texture is generated via a Depth Prepass, URP uses the Opaque Layer Mask at the top of the Forward/Universal Renderer asset
  to determine which objects should be rendered to the depth texture. This feature can be used to render objects on *other layers* into the depth texture as well.

Afaik in Unity 2022.2,

If URP uses a Depth Prepass :
  - The depth texture will only contain opaque objects, based on the Default Opaque Layer Mask 
    at the top of the Universal Renderer asset.
  - So if you remove a layer from that and instead render it with RenderObjects features, 
      those objects no longer appear in the depth texture, even if their shader is writing depth :(
  - Same goes for any Transparent objects with ZWrite On. The depth texture won't include those

// Can remove filter text at top of object picker to see all gameobjects again.
// To allow scene references, add second param as true. e.g. :
