Summary0000108: Ambients don't light sides facing away
DescriptionCreate a room with some pillars, and stick an ambient light right in the middle, covering the whole area. In render mode, the back faces of the pillars will not be lit. I tried both "Do not cast shadows" values on the light properties, and several different ambient light textures.
TagsNo tags attached.

Known issue -- ambient lights have been fixed for models, but they won't work properly for brushes.

I think this can be fixed since last year's lighting system refactoring, however I don't know if anybody is actually using traditional Doom 3 ambient lights now that the mod has the ambient_world system.

0000108: ambient lights now render correctly

Ambient lights had in fact never worked since the switch to GLSL, since the
ambient light code was only ever present in the old Cg shaders. The GLSL shader
is now updated to support ambient lights through a new bool uniform, which
works for both models and brushes.
