    I get that too have you tried increasing the resolution and also increasing irradiance?

    Also turn off UV optimize if that dont work. usually when i get a bright problem on an edge or corner ive notice its a problem with the Rays hitting normals during light transport meaning somewhere in that area it is hitting a backface possibly.

    Forget to use Planes or quads for walls and floor. always use an thin cube as wall and floor to get the beat result on lightmapping
