Current questions and answers regarding the map editor.

Hello, I encountered a small problem when trying to create my own map. Any items that have their own tiles (it doesn't matter if they are red or green, like the stones in the background) work properly. At the same time, objects that do not have their own tiles, but only a model (which a hero can move around on, like the grass and stick in the foreground) are visible in the editor, but are not displayed in the game. What could be the problem?
