Falling through the landscape in open world

I created a empty open world level and filled it with a landscape, built the level (lods etc) and set loading range for the level partitions to very small. When I play and start in the middle of the map and go further then then loading range i suddenly fall through the landscape!? Or it all turns black.
Whats up with that?!

Hey @Luckieluuke!

Yeah, unfortunately that’s exactly what you should expect to happen when you set it to very small. :frowning: Typically that’s for a project that you would move very slowly, like a horror game or something. I’d set it to at least medium if you’re going to move at 600u/s or faster. The level has to take time to load, so what’s happening is you move faster than it loads.
