> The tiny peak at the edge is probably because the edge between the two walls sometimes has white paint showing through, so it's not a lighting effect.
I vaguely remember an old graphics professor mentioning that this peak would exist because of reflected light from the other wall, though I can't find any literature after some light googling. Is this a real thing, or am I crazy?
