While this works for most games, it can easily lead to performance issues in 2D scenes relying on physics as the number of bodies is extremely wasteful. The system has been reworked from the ground up. Now, ``@[TileMapLayer](enginetype)`` physics merge cell shapes into bigger collision shapes whenever possible.	name github Gilles Roudière groud	https://github.com/godotengine/godot/pull/102662	/storage/releases/4.5/video/godot_chunk_tilemap_physics.webp	/storage/releases/4.5/video/godot_chunk_tilemap_physics.webm	left	[@groud](https://bsky.app/profile/groud.bsky.social)
