i'm using 6.50. actually i sort of figured part of it out. In Med the origin wasn't in the center of the model, that seemed to fix it. there's still a problem though. Now that I moved the origin, the model is (for instance) lit by the blue light that's in the level, BUT... it's evenly lit, so I lined up 6 of the boxes touching each other down a hallway and the one farthest from the light is dark, and each one getting closer gets brighter. it's even though, it's not a gradual change (if that makes sense). I guess I don't understand how the lighting is applied to the models. do i need maybe more polygons on the flat surfaces so the lighting can get re-applied to each polygon, thus creating a gradual change in brightness across the model? Thanks
