To better illustrate the issue with the lighting, I’m attaching a couple of screenshots of the issue, one showing what it looks like when the issue occurs and one showing when the level instance loads normally. Both screenshots were taken of the same room, spawned in the same position, on two different runs of the game. I did notice that, when playing in the editor, if I eject from the player and select a mesh that is missing lightmaps in the editor, the lightmaps for it suddenly load in, but there’s no way to fix the issue in a packaged game that I’m aware of.
