.addComments(" Where this is important is in floors (and walls). If you create a floor using one large face (or the top of a Box node), then put a point light at the middle of the floor, the floor's corners will all be equi-distant from the light, and thus will have the same, rather dim brightness. When this brightness is interpolated across the face of the floor, you'll get a constant dim brightness... even directly underneath the point light! ")
.addComments(" To fix this, use a mesh (face set) with lots of smaller faces. Now, each face still has brightness computed for its four corners. However, the small faces near the center of the floor and the point light get higher brightness values computed than those more distant. This will give you a brightening effect under the point light, and a gradual dimming towards the edges of the floor. This is much more realistic! ")
