Lightmaps load in at a low resolution?

Hey,

I have an issue where, after I load in a map (using Open Level node) the lightmap is in a low resolution, and it takes a few seconds until it loads in correctly (making a visible pop when loaded). It happens in the editor and in standalone builds as well. Here is a GIF] about the issue (this same exact thing happens in the game not just in the editor).

What am I missing? Is this supposed to work like this, or is this an engine related bug?
I’m using version 4.24.3.

That’s normal, it’s texture streaming

Do you have any tips on how can I hide it? A loading screen is the way to go I guess, but how can I check if the textures are finished loading (or streaming rather)?
