Thanks so much for the quick replies! At least part of the problem turned out to be specular intensity turned way up. Still, I think the lighting looks weird, as it is too intense at the surface directly facing the light source, and abruptly fading to black when the light hits at an angle: https://i.imgur.com/RS4qHBS.png Maybe increase ambient lighting? Don't want the dungeons to be too light though. Any ideas?
