Landscape Region looks empty

Hello,
I’m trying to create a simple terrain But I’m facing this issues where,
I Import a Heightmap, then assign a material for layers from Lush:Stylised environment asset,
and then clic impport,
then I get this:


After this, the mouse scrollwheel doesn’t react and I can’t zoom in/out or do whatever I woulld like to do.

Haheummm…
I decided to re open the level without saving and got the terrain mesh

Hey there @blackantmaster! Did that restart correct your issue?
