Why is there no mouse or keyboard input when you spawn below the grid?

Hey everyone,

Basically here’s the full sequence of events leading to the problem: create terrain in world machine, open default ue4 fps template, import heightmap, delete all the template walls and floor and stuff just leaving the lighting and character objects, try to spawn on the map with terrain material created and lighting built = no input from keyboard or mouse. Once the terrain is elevated above the grid, problem resolves itself. Why is this happening?

Sounds like your KillZ in your World Settings is about 0? try setting it to -100000, that should fix the issue.
