URP v12: allow users to prime the normal buffer before gbuffer

Hi,

Currently with URP v12, there is no way for users to specify a custom object should render into normal buffer when they are filtered in the URP renderer.

URP v12 does render a depth normal pre-pass if it sees an object with complex material like Clear Coat, BUT users cannot force it on objects that rendered through Renderer Feature (or Scriptable Render Pass).

We would like to have that option, as DepthNormalOnlyPass are lockdown as internal, there is no way to do it beyond changing the package source.

Please enable us an option to do that without forking URP.

Thx!

A update on this:

This is possible via a custom Scriptable Render Pass, I ended up duplicating code from DepthNormalOnlyPass.

One thing I should note is, somehow I didn’t have to call cmd.GetTemporaryRT and cmd.ReleaseTemporaryRT in my custom render pass.

If I call them then Deferred Pass are no longer able to bind the normal gbuffer. (even funkier is SSAO pass somehow can).

No change to URP package code was necessary.
