“Large World Coordinates” improves the world coordinate accuracy, allowing you to create larger worlds. When enabled, it will turn off “world bounds checks”. In addition, Enable world bounds checks: uncheck, valid for both editor and PIE.
That makes sense. So how can the world disappear because of the lack of precision? In my previous experiments moving very far away would made the level unstable (movement, rendering artifacts) but never disappear. What is going on? Culling? Bounds checks? If bounds checks, why doesn’t it work as expected with World Bounds Checks and the LWS flag set to false.
