UE 5.6 Runtime Virtual Texture Not Working.

Hi there! I’ve been struggling for months with runtime virtual textures while using Bushify on my landscape. I don’t know what I’m doing wrong. I followed tutorials and I always ends up with my landscape turning black. Any help would be greatly appreciate!

Thank you for your time.
