Lightmap Baking Error

Hello, i’m having this new problem in some of my meshes. Everything is set up good: production quality baking, lightmap channels set correctly, none of the lightmaps have overlapping.

So the weird thing is that im actually re-using some meshes from previous projects, which baked perfectly before. I don’t know if its the 4.24 version that is messing up the baking, or what could be the problem?

Maybe there is a light inside a mesh or very close to some other geometry like a wall. I had something like this happening and it was a light being too close to the ceiling.
