I know that Q3map2 supports negative lights. My question, does it support negative lights emmitted from a shader or is it just point based lighting?
EDIT: one other thing i forgot to mention… when a q3map2_sun (or the likeness) entity light is created, is that sun light global to the entire map, or just the area its placed in?

Negative shader lights should work, but I haven’t tested them.
Suns are global, parallel infinite lightsources. They light up everything, everywhere.

Yeah I’m confused on the negative lights thing… A screenshot example?
Would it be possible to invert colors with a light? Sort of like berserker in Doom?
The original RTCW q3map supported negative light entities, but AFAIK, they never worked in q3map2. Never felt a huge need for them myself…
edit:
Matt, the negative entitiy lights were were just what you’d expect… a ‘dark’ rather than a light.
Well thx for the info Y… i was hopin to just have a sun light light up one room… oh well… ill just work around it… Bounce the crap out of that room i guess…
This is a negitive light, (upper left corner of screenie)
*taken from shaderlab.
Basically a negative light is a point/ shader based light that “sucks” up all surrounding light no matter how bright the light is… im assuming that setting a given value to it will make the radius larger or smaller… enough chit chat… ya get the picture.

Actually it had these crappy “darklights” which replaced any light value already at a sample with its value. They weren’t really much use.

So if one were so inclined, they could make more detailed shadows in an extremely well lit room…
…blah, I’ll go make a quick example to show a good use for it. Assuming this works in Q3…
If you were going to go to that kind of trouble, just make yourself some badass shadow maps in photoshop and apply them as “filter” decals.
/Me is thinking about SeriousSam2-like running shadow blobs via lightstyles in a long hallway…
All theses features… sigh
Well this is how i was going to use it: a ‘bottomless’ pit where the bottom of the pit gives off a negative light so that it will fade to pitch black… As of now, im using an ambient light value (yeah i know about _minlight and the like) to light up all dark areas, but i dont want the bottom of the pit to have a defined area. Thus the negitive light will be used so that it will fade to black… i may use fog, but it all depends on the final outcome for that room… FPS wise. Thats how im going to use it…

Well my draw to negative lights is because (I assume) they effect the light grid. For the really detailed stuff you’d want shadow decals anyways, but for large over-head beams or the like where a player standing under one should actually be darker, it seems a negative spot light is the solution…
