Question
I want my tilemap be able to cover more cases but it removes the simplistic stuff I liked about it before.
Tilemap 1 is the one that has more stuff and Tilemap 2 is the one that has the less, simple stuff
You could consider using multiple simple TileMapLayer’s drawn over each other with the same theme. You can then cover cases by combining them.
Any performance cost you may fear - I predict -will be negligible.
In this example I just use a different layer for the grass on top of the dirt:
Maybe that helps?
