First Killzone screenshot/details? So says USAToday..

Why ?
 
I´ve heard that it has already been downgraded, No day and night cicle etc.
Would be massively helpful if you can provide some links to KZ2 GA feature set. ^_^

Dont know if it has been completly removed but since they are using static shadows then it would seem so.

Fran had some interesting things to tell from the tech presentation.

I was at the presentation yesterday. Some interesting ideas. Overall, dropping HDR, 4X MSAA for 2X, using only 12 (6) taps on 512x512 shadowmaps for the main directional light, dropping specular color for materials, dropping directional lightmaps, dropping shadows and per-pixel lighting on particles, only one lighting model for the entire world, for the sake of more lights (actually, for the sake of lighting performance non-dependent on the geometry but only on fragments lit which would be desirable) didn't seem worth it to me.

But I still hold to the idea of Deferred Rendering, the architecture is so simple and natural it hurts it's not a win this generation. I'm sure I can go deferred without sacrificing flexibility for the artists when DX10.x like hardware is standard on consoles too.

Ah, The Art Of Cryisis presentation was absolutely ace, the most interesting I've seen in years and I was the only coder in it. Those guys know their stuff.

If I remember correctly, they have a IBL solution for dynamic objects based on SH and computed in parallel on SPU, which is written to the albedo component in the G-buffer. Using the SPU this way is a pretty cool idea.
It looked like they don't support different time of day, since they pre-compute a single component directional light occlusion term (basically static shadow term). It's interesting how they use this term to stencil mask the deferred lighting computation of the main directional light, which gave me a couple of ideas.
 
About static shadows and lights, I found this very interresting.

They were later talking about more than 100 on screen real-time lights and around 10 on-screen shadow casting. I would not like to build forward render engine for such requirements. I think most of the trade-offs they made seem reasonable with these numbers and I think 4xMSAA and directional lightmap might be too much extra memory, but who knows why they don't have it.

No, what I meant was:
Was day-night cycle planned into KillZone 2 in the first place ? We were only told about weather effects as far as I can recall. What official day-night downgrade are we talking about ? Most of us, including myself, are just speculating here. :|

Come to think of it, for an FPS, do you always have to fight during day break or dusk (for the day <-> night switch to happen), or do you fight for so long that the day changes to night (and vice versa) ? Can't they go to a different level for day or night combat ?

Well all shadows are not static of course. But since there are static shadows in the game (probably for buildings and such) then day-time cycles would look strange as real-time shadows wont point at the same direction as static shadows.

I imagine they get up to a high amount of real-time lights when summing in the muzzle flashes, building lights, explosions, and weather like thunder rays etc (like in Stalker for example which uses a DR engine to).

Suppose you fight at sunset, in ~30 mins the sun has disappeared and thus things get dark. Now imagine seeing how the shadows change position and gives new hiding points and impresses the player! :smile:

I guess that is why they choosed to not have day & night cicle in the game.

Indeed that would be very impressive. In fact I have already seen it......in a other game:D

Supposed ? It is not a downgrade _if_ none was planned in the first place ? Otherwise, every game without this feature would be a downgrade from day 1.

If the Sun has disappeared, can't they remove the static shadow totally and leave the dynamic lights only to work their magic ? (I am genuinely asking a question here).

What do you mean with: "dynamic lights only to work their magic "?

Of course, but there was some talk about daytime changes in this game. May have been speculations though (Im to lazy to go out on a link hunt now!)! :smile:

When the sun disappears it is dark, I am talking about daytime until it gets dark!

If sun still up then > Not really since then it would be better to not have the static shadows from the beginning. Since the sun moves constantly and so does the shadows direction.

There is no downgrade that we know of. Fran was talking about possible features set (HDR, day/night etc) not the initial specs of K2. Some certain group of people choose to interpret that as a downgrade as expected.

Realtime day/night cycle would be an overkill for linear FPS where gameplay is discreetly levelized. I would expect Killzone 2 more old school in that sense, as opposed to Far Cry or Crysis. Offline cycle is always possible of course.
 
If the stormy wheather in the game is caused by weapons that Helgahst controls and you destroy theses weaopons so the sky clears from clouds would make a time-of-day'ish cycle. :smile:

Anyways, it seems like Guerrilla tailors this engine for the game and gameplay instead of, for e.g Crytek where they put all effect and techniques they can think of in an engine, and then build a game out of it - like an afterthought.

[Looks to Okaban]

Isn't it possible to implement "changing shadow" with dynamic light for a particular sunset level, or even a night time level ?
