I wasn't sure what the normal name for this problem was, tried searching but had no results.
Anyways, I have light bleeding through where two faces meet. There isn't an obvious explanation in Radiant. Does anyone know how I might fix this? Thanks.
Can't see much of that picture, but most often light bleeding occurs when two rooms with a wall inbetween share the same floor brush or something like that. so start splitting some brushes i'd say.
