When a landscape is set up to use runtime virtual texturing.

If it uses a material that writes to a runtime virtual texture and has tessellation enabled.

Then we see a crash and the log reports:

Shader expected a uniform buffer of struct type LandscapeContinuousLODParameters at slot 3 but got null instead. Rendering code needs to set a valid uniform buffer for this slot.


This was reported in:

Steps to Reproduce

Open TM-RuntimeVirtualTextures map in QAGame project

Open Landscape_RVT_Mat material

Set the D3D11Tessellation property on the material to "Flat Tessellation"

Observe the crash
