Virtual Texture Streaming - Any good resources out there?

Yes thank you. I was just kind of confused about how VTS was being used in the Valley of Ancients demo. It seemed like it would have been more efficient to batch things together than have each instance have its own virtual texture. But i guess they just wanted the max 8k per instance. I’m confused about how efficient nanite renders different material instances (or nanite draw calls?).
In theory, couldn’t you combine all objects into a VTS material (maybe using the UDIM workflow in the docs) and then nanite will render a single material instance for everything, and VTS will decide how to load smaller sections of the giant texture into memory? I’m just brainstorming, i know such a material is impractical. But it would be useful to know how these things work together for making assets and such
