Ok, it appears that Virtual Texture Streaming is different than Runtime Virtual Textures? (the VT label I’m seeing on Megascans textures) Looking for a good tutorial on this, because I’m thinking I need to distinguish between RVT and VT streaming, or is it the same thing or option B, is as simple as swapping out nodes from a traditional texture sampler to a Virtual Color Normal, node but I’ll guess it requires more than just this…
