Volumetric Lights

antarez

<div class="IPBDescription">still implemented ?</div>There was a video podcast on the ns2 site i can remember, where you could see an old command console and volumetric lights falling through a shutter.

I just wanted to know if someone could tell me if its still part of the engine and will be in NS2 ?

regards

Yes it is still in, but the public doesnt have the build that utilizes it yet.

Draco_2k

This functionality is currently locked along with most of the others. Yes, it's still in.

Hope this dosen't get cut, nice to see it done properly instead of it being faked, like in most games.

Consider I'm sure I heard it referred to in a podcast or videocast as being ns2's 'signature lighting style' I'd be surprised if it got cut.

What do you mean it's not in? I could have sworn I saw the dynamic lights in the map editor. Are those not the same as the effect seen on the videocast?

I'm actually curious about the volumetric lights thing. teach me! ;)

Yeah this got disabled when we were doing performance tuning but I'm sure it'll come back in the near future. We love it too much to lose it!

I managed to get my shutters to work well enough. It was a bit of a pain though

Yeah, it really is a great effect - plus, with some of the things we're planning for the maps, atmospheric lights will really make a difference.

For those of you wondering what we're talking about, here's an early test shot that includes volumetric light effects:

Volumetric lights and dynamic lights are not necessarily the same. A light could be one, the other, both or even none of the above.

Dynamic lights will light and cast shadows on and around objects that come nearby.

Volumetric lights are lights that appear to pass through smoke, dust, fog... Think of very bright sun rays finding their way in a dusty dark room or the beam of a flashlight in the fog.

I might be wrong on those, but am pretty sure this is it.

Edit in: there are also 'static lights' which don't affect moving objects (characters, weapons, moving props) but are usually rendered in place.

Sir, can I ask you for a higher resolution of that screenshot (1680x1050 :3), pretty please?

Insane

Unfortunately not - I don't have it to hand but the original image can't have been wider than 1280px. Any new version of that shot I could take wouldn't include atmospheric effects.

Thanks! So the volumetric lights are the one that shows beams in mid air? That makes sense, being as the beams show volume. Whereas just casting a dynamics shadow on a wall has nothing to do with volumes.

Now I remember that the light beams one could see in the videocast are not present in the map editor (or game either it seems).

Pstrangler

Yep. In the pic posted above you can see that the light behind the fan has both volume and shadow as, in the shadow of the blade you don't see the dust 'volume'.
