My ep2 maps were coming out much brighter than i expected, and i found that the vgui/achievemtnts/... textures emit light. I also had a room textured with Alyx Vance's face (don't ask) and noticed that it also emits light.
Is there a list or way to tell what textures emit light like this--it's not the lights.rad file, because none of these textures are in der. Also, is there a way to make them NOT emit light, in case a situation called for it?
