clay, I'm not worried about it, I learn by fixing, my Dad taught me to fix just about anything, it's all about creative problem solving, however, I always have some parts left over after fixing things....hmmmm.... Actually, no, tjohn, my Bryce just randomly picks things for refraction unless I'm using water or glass then I have to set it up....strange, I set it to 0 and the ferns are fine now, go figure....:)
