Foliage is getting spawned where no landscape is and it’s just floating in a pillar in the air.
There’s not even a surface material that should spawn the foliage over where it’s hovering.
PLEASE HELP ME!
Okay I was able to fix it by deleting the landscape section under it and just re-adding it. Very scary I have alot of time in this level and I never made a back-up. I think I’ll make three now
Hello,
You found another way of fix this problem or just deleting the landscape and creating another? I’m having the same problem
