You can visualize the game's spawn zones to see exactly where players can appear.
You can draw Red Boxes to show the raw boundaries of the spawn areas defined by the map.
You can scan the terrain to generate Green Tiles, indicating valid ground positions where spawning is possible (it checks for floor angles and obstacles).
You can adjust the scan density, speed, and tile size using the sliders in the menu.
All menu actions are available when the menu is open (the toggle key is "F1").
