Solving light bleeding (HDRP)

Hello! I’ve been working on this model for a while but in a certain corner there’s always light bleeding through. The lightmap scale is good, the UVs do not overlap, yet this light bleeds through? I’ve done everything from trying to bake with a shadowbox encasing the house to absolutely making sure the geometry is truly connected (also in the hand unwrapped lightmap). Yet light still bleeds through. Does anyone have any ideas as to how I could fix it?

I’m using lighting mode Shadowmask with mixed lighting.

which light mapper are u using?
what is ur resolution?

Hello, can you post a screenshot of the texel validity view please ?
You can activate texel validity view by changing the Draw mode of the Scene view, it’s on shaded mode by default.
