Yes, in the cavity-type scenes I've rendered (such as a room with a single
window admitting light, or a cave), you really need to set recursion_limit
above 2. I typically use a recursion_limit of 7 in such scenes. I also have
gone up to 12 and seen quite a visible difference, but around 5-9 usually
works well.
