Adding an instanced large TileMap with add_child results in a lag spike

I have a TileMap in my Scene which I store in a variable and then remove from the scene tree with “remove_child”.
I then create a Thread to fill the tilemap with a large number of cells to create my world.
When the thread finishes, I add the TileMap back into the scene with “add_child”, but this causes the game to freeze for several seconds.

Is there any way to avoid this lag but still be able to use a Thread to fill the TileMap? Since you can’t access the scene tree from a Thread I don’t see how…

Can you try calling the add_child method inside a call_deferred method?

It already was inside of a call_deferred method, called by the thread at the end when it is done adding tiles

Hey, did you ever find a solution to this? I have tried multiple methods at this point. chunking as a small part of a bigger TileMap. Chunking as a larger map but each chunk has it’s own individual map. etc etc. I still get lag.
