    I read the forum thread, the blog post as well as the doc about the new SRP API. I get that we can do custom lighting, culling & filtering with it. I also understand how forward, forward+ and deferred work. However, I don't understand enough about the UI rendering pipeline that is currently in use. Where can I find more information on this? Is it possible to create a UI only pipeline?

    Also, do you have any recommendation on resources to understand more about UI rendering in general? Like how its done in popular OS

    Thanks

    Someone correct me if I'm wrong, but the UI system consists on a bunch of components that make easy to place, scale and interact with 2D UI elements. But they are actually 3D quads that are always in front of a camera with their own set of shaders. So technically there's not much difference from other 3D objects. So I think that what you are asking should be possible.

    According to the Frame debugger, they look like forward rendered quads. So I guess yes.

    Now I need to figure out if they do static culling by default or how to implement it.
