So I can't figure out the lighting setup in the model preferences settings. There are 4 lights you can turn on and I can't figure out what xyz coordinates to put in for any of them. I left the default first one on and it seems like when I fiddle with the others they just get darker. Can someone elaborate how the coordinates tie in to the lighting direction? Optimally I'd like the model to be bright from any viewing angle not just the high top view I'm stuck with now.
