Virtual Texture all grey in UE 5.7

Hi Guys,

I’m trying to setup Virtual Texture using Landscape material and everything is just grey.

I have enable VT support in the “Project settings” as well as converting all texture to VT.

I have created RVT and inserted it to Landscape itself

I’ve also loaded the VT under “Virtual Texture Sample”

Everything turned grey as soon as I setup those.

Any idea how to fix this?

Thanxs.
