I have been trying to make a 3d game, [https://arcade.makecode.com/S99882-03620-05841-07819](https://arcade.makecode.com/S99882-03620-05841-07819) , but the floors in my project don’t appear. To sum it up, any tiles on the tilemap that are not marked as walls do not appear in the game, I have seen it done in other projects, but it doesn’t work in mine. I don’t know if it’s a different extension from the default AqeeAqee extension or what, but I’m kinda new to this whole thing so idk. I’ve seen it work on a few games, like this one [https://arcade.makecode.com/S53987-45428-75480-18314](https://arcade.makecode.com/S53987-45428-75480-18314) . If you know thank you 😃

Sadly the extension doesn’t work like that. the floor tiles are coded in through javascript. It is not part of the official extension. I think it was planned to be added though.
