When I light mapped my room I got corner leak problem. Please see the attach image. In the corner of the room the light is leaking. How to stop this leak? There is a omni light in the room and directional light outside the room.

    I don't understand what solid means! Cos I tried to make the wall solid and also the room as a box, means joined all wall, floor and ceiling but no luck. It still bleed.

      BirdaoGwra I think it means that each wall is a box instead of plane.

        If I make all wall, floor and ceiling box, it only works on some places not all places. The light still bleeds.

          It's a guess, but you might need to either:

          1. Increase size of the walls so they overlap
          2. Use a single mesh for all walls

            1/ I tried both. I made all walls, floor and ceiling a single mesh.
            2/ I made all walls a single box and all of them were overlapping each other.
            But the light still bleeds.

                Maybe you should post a sample project, so people can see what you're doing.

                BirdaoGwra I made all walls, floor and ceiling a single mesh.

                Single(edge/vert connected) continuous mesh. Not just join them into a single object.

                    BirdaoGwra Here I made a test scene.

                    An option is to simply double the thickness of the walls.

                      Increasing the thickness of the walls is not a good option for my map. B'cos I have already made my door frame too much thik. But as cybereality said, I made the inside rooms solid water tight seal and the bleed is almost gone. Thanks for the reply and help.

                        Do you mean that it is a single solid (merged) construction? Not separate walls and floor and ceiling?

                          No this is not a single solid room. Walls, floor and ceiling are all separate mesh. I just blocked all my interior with a cube 🙂 and the bleeding is blocked by the cube.

                            So, through the windows, can't see the surroundings?

                              Once lightmap is baked I just hide the cubes.
