Hello all, I've an issue that I need to fix

I've been working on a map of mine and after I ran it, this happened between 3 brushes

They have the same lightmap scale, and no props that would mess up the lighting. There's a room inside this building as well, I've also ran into this problem with a few other maps I've made

I'd appreciate if someone tells me if they know

Thanks!

Do all of the brushes have the same texture alignment? If so, have you tried putting all those faces in the same smoothing group?

Is the texture aligned? Hold alt and right click to align the textures on those faces. Also, if you don't have nodraw on the non visible faces lighting can bleed through.
