Hi all !

I found a case that I can’t manage to fix :

a simple room lit by a point light with a window and a cube on the outside.

After baking, there is a huge light bounce between the outer wall and the cube :

Here’s the scene if someone want to take a look : Dropbox - Lightmass_Leak.7z - Simplify your life

I Just rebuild the lighting on your level for testing and there are no light leaks what so ever, even I am not able to replicate the error.
