How to Setup Runtime Virtual Texture (RVT) and Blend Materials in UE5.3

By setting up the Runtime Virtual Texture (RVT) we can organically blend landscape's/surface's material with material of any asset that comes into contact with that landscape/surface. Unfortunately, as of UE5.3, nanite meshes cannot write/sample RVTs, so by making the static mesh non-nanite allows this to work correctly.

CORRECTION: at 7:56, the second Transform Vector "from world to tangent space", should not be at Landscape Material section, but it should happen after two material blending instead. Furthermore, an additional Transform Vector "from tangent to world space" should be added for other material as well. Basically, Normal texture's space has to be converted to "world space" before blending materials and after the blend it has to be converted back to "tangent space".

You can use a vertex normal ws mask and use the z component to subtract from the rvt world height

Do you know if RVT can be used with splatmaps? I trying to add RVT to a material layers using layer parameters and it is not working.

Check triplanar mapping for perpendicular faces
