The Keystone to Great Lighting

[Kman]

I've actually seen quite a few people have trouble with shadow quality when they make large spotlights for sunlight.I haven't tried it myself,but a solution to that might be to just duplicate a semi-large spotlight a bunch so you have many individual spotlights closer up, which might solve the problem. I don't know though,it's just a theory, haven't actually tested it out.
