I know some folks who have just used it anyways commercial, waiting for him to respond to send the payment. They're going on good intentions and all. I personally don't have to worry about the situation as I'm not using it commercially, and there's not really any good advice to give on if you should or should not do it, so it's up each individual really. It is frustrating, as he has one of the best lighting systems out there. I've messaged a couple coders trying to get the light issue fixed further (the code I posted above works on lightweight games, but not anything more in depth like busy or large maps, etc). As soon as I have a solution I'll post it here as well as the other thread I mentioned.
