Issues with Virtual Texturing

I’m not too familiar with Unreal Engine so if someone could point me in the right direction that would be great!

I’m having issues with Virtual Texturing my landscape material. When I set it up, it just seems like the Virtual Texturing is breaking when it tries to render it? I must be doing something wrong or it’s not supported? Before getting to Virtual Texture Output it goes through a lot of lerps and other math that I don’t understand (not my material). Images are attached of the nodes of before and after using VT. I’m showing normals because it’s the best way to see the issue, but it’s happening to base color, specular, etc.

Hopefully someone can make better sense of this than I can.
