A very nice feature gives a level with detail more feel and generally looks kick *** :). Loved how it works on animated models.

I'm so glad the light itself doesn't need to be on screen in order for these to work. Post processing lightshafts are cool and all, but make no damn sense.

PP light shafts actually makes sense if it is foggy. Your Eye reacts like a lens of a camera. You will see light shafts almost like you see it in a pp effect. Light shafts like in this scenes are also logic compared to real life, because then they will show up when there is a lot of dust in the air or when it is foggy.

Nice sweet done btw :)

Unfortunately we will likely end up doing a post-process for directional lights (like the sun light), because they're huge and this ray traced approach would be stupidly slow there.

I hate it when it disappears because the light source is no longer on the screen, but I guess we'll have to live with it :-(

My biggest irk with post-process directional lights is they tend to have strange artifacts when a complex object is partially on, partially off the screen. As an example, sun streaming through a tree, which you aren't looking directly at, but still have some foliage visible on the screen. The artifacts are most annoying while the camera is in motion, which is even more unfortunate.

Stuff like that with the sun is fine imo. lightshafts from the sun never made too much sense to me anyway. There are only really rare occasions where they'd appear in the fashion they do in most games... most of which would result in extreme atmospheric haze along with the effect (which is never the case). Crysis and Gears 3 would be the biggest offenders of this.

Having this effect in dark dusty areas like you have been showing in this demo is great though.

When it comes to outdoors lightshafts, I would prefer it if there were small volumes of the effect around the ground (15 ft at it's highest) to simulate pockets of not-quite-settled dust. Would make more sense, though I have no idea how it could be done.

They DO happen in real life, but it's not something I care about a lot TBH. I still want to support the feature and let the level designers decide if they want to use it or not. Since it's still a quite expensive feature, users can of course disable it for better performance anyway.

Oh, I know they happen in real life. I do see it quite a lot :P

What I mean is that they're usually featured in games in environments where they would never be. It's like lightning with no clouds.

Yeah I see your point. But what game is 100% realistic anyway? :-P

As long as the effects are not overdone and very exaggerated and everywhere, that's fine for me.

So what you're saying is you won't go Crysis 2 with it? :P

What I'm saying is... erm... well I haven't played Crysis 2 so I don't know what you mean. I didn't like the first so I didn't bother with the second.
