After creating a landscape it wouldn’t appear in the world and the only thing I changed was the number of sections to make my world bigger.
I did some testing and the max size a world could be before it didn’t show was 16 by 16.
forgot to add this: system specs cpu Ryzen 5 5500 64gb ddr4 trident z ram b550m-c motherboard, adata 800 legend gold nvme, gpu was rx 6500xt 4gb now 1060 6gb
