I understand, I just found your example very good. My intention with the project would be more for study, as I loved the lighting effect. If you have any tutorials on how to do this, I would appreciate it instead of sharing the Godot project.
I did this using a property you can add under TileMapLayer > Tile Set > Rendering > Occlusion Layers
This tutorial was really helpful to me back then. I hope you find it useful.
thank you very much
