This feature only exists in the legacy renderer and thus is not listed in the menu anymore. Set 'gl_lights_additive' to 0 at the console and you should be good to go.

Then you might be doing something wrong. It works for me without an issue. Additive lighting is also a lighting style - which would end up making this mod to look very terrible.

If you're using the more modern GL3+ code path, that option doesn't do anything since the renderer doesn't have that capability. It only works for the GL2 fallback renderer.

And the only reason for that is performance. The feature doesn't make any difference for shader-rendered performance and looks like crap so I never bothered. In GL 2.x it saves an entire render pass over the entire scene.
