Runtime virtual texture is broken if displacement is used in a landscape material. (currently using 5.6)

So im using 5.6 and when i enable nanite “build data” it breaks my RVT display if i have anything hooked up to the displacement… even a solid color value with no texture. My goal was to make a seperate RVT just for displacement but i cant even get it working with a solid color in 5.6…

First screenshot is non nanite terrain using rvt.. And the second is the result if i do build data to nanite while anything is hooked up to displacement. Any idea if this is a bug or if im doing anything wrong?

Seems like this bug was caused by the plugin LANDSCAPER System form Ludic Drive. If anyone else has this problem do not create your terrain with it automatically setting up size. Input manual settings for the number of sections and all that. Then it works fine.
