I know about "A". Simple, place a light down, IE Officelightfillneutral and it does not update the light data in my map. Also, let's say I load Doc Johnson's house in Good Springs. I move a light effect and it then turns off in the GECK. However, I can save and load and that moved light appears in game. Then I reload the esp in the GECK and it updates the previously moved lights that broke in editor and they are now functioning. Move them again and they break once more. I was watching the video tutorials, it seems the lights in the tutorials are constantly updating. What's the deal with my GECK? L, M, A, all do not update my lights in the editor.

GECK (New Vegas Edition)
1.1.0.262

Oh, and what's with the CTRL+ALT+Left click to add lights to fixtures and stuff? The tutorials on http://geck.gamesas.com/index.php/gamesas_Tutorial_Lighting say to do that when adding lights and glowFX to light fixtures or fixtures to ceilings, but CTRL+ALT+Left Click simply selects whatever I click on.

Well first, since this is for the NV geck, it belongs http://www.gamesas.com/index.php?/forum/111-the-geck-fallout-new-vegas/.

Second, this has been a comfirmed (Suspected) issue with the geck. Along with Havok, lights do not update properly for some reason. You can read more about it in http://www.gamesas.com/index.php?/topic/1131674-no-lights-in-geck/.

And your Ctrl clicking and all that is for when your using the Object Pallette. Otherwise I don't think it does anything.
