Ok gnna attempt to answer. I was way off… It seems like Virtual Texture Streaming is meant for just really large meshes and textures where you only see a small section of it or small area closer to the camera so it can only load that specific section at high res. But doesn’t this require that the UVs be laid out evenly on the texture sheet? If the UVs are distributed around on the sheet wouldn’t it just have to load all the tiles anyway?
I’m still curious though… could VTS be used as a nanite optimization to bring down the “nanite primitives”? Say you have 64 unique objects and textures at 1k that are used a lot in the world… and you batch them into a single 8k material using the correct tiles… and let VTS sort out which tiles to load into memory. Or is nanite already doing something similar behind the scenes?
