Hi I have a problem with the lights I managed to set them in the SCN and in the game work. The problem is that they cross the objects, illuminating areas where the light should not reach. The lights are inside the box but they can to illuminate the roof of the balcony above them. Then I noticed that putting the lights in Blender the same thing happens. I checked there were no holes in the mesh, but it's all right. you know how to fix it, if it is possible? Thanks EDIT: How many lights I can put on a track?
