No Floors

[MrBehemoth]

Even a plane with no texture at all should still be solid. Weird, especially if you've tried all of those things you mention - and if there're no bugs in the log, and deleted the cache.

A few more things to try:

- What happens when you move it? i.e., just put it somewhere random like at waist height in another room.

- In game, point at in "inspection mode" - is there anything there at all? e.g. a non-solid black plane, or is it just open void?

- Check the name of your plane, open up the map file in your text editor and search for it by name. Spot anything unusual?

- Select everything except your mystery plane (use Ctrl-F). Export it all to a .expobj file, then import that back into a clean map. Now try re-creating the plane.
