    [EDIT: this thread is about the bloom effect only, not HDR. Updated the images to better explain what I'm looking for.]

    Sup everyone!

    Anybody knows if it's possible to add bloom to a map without compiling HDR?

    For those who don't know, I want to add this effect:

    Full screen for all players.

    I've tinkered with screenoverlays, but I can't seem to be able to add bloom using it.


    Thanks,

    Why not just compile in HDR?

    Well, it's going to double the size of my map, and I'm worried about the performance reduction.

    Can you add bloom using color correction? I doubt it.
    It would be great if you could make some colors bleed, but I doubt it can do this.

    The reason you compile with HDR is to get HDR. That's why it's there, and what comes with it comes with it. That's the engine. You're not going to get HDR without using HDR.

    Well, that's exactly the point. I don't want HDR. I want to try bloom without the use of HDR. (for the above mentioned reasons)

    I'm asking in case someone knows how to enable bloom separately from HDR or use a shader or an entity to mimic the effect of bloom.

    In source, HDR is supposed to emulate how our eyes adjusts to and how it is effected by light exposure.

    In other words, HDR is bloom. What you are asking for is nonsense.

    Bloom was used in games since the PS2 which couldn't even produce HDR.
    Brightness accentuation around bright objects. Like shown in the OP. THAT's bloom. :)

    So, if anybody has a trick of their own, let me know. I'll check back during the evening.
    I'm compiling HDR just to see if the performance impact is major... if it's not, HDR it will be.

    Thanks for the replies and the Super positive support everybody.

    EDIT: if this can help you guys actually understand the "nonsense" I'm trying to explain to you, check this link, it shows the difference (scroll down) between no effect, bloom only and HDR in the Source engine:
    http://www.tweakguides.com/HL2_6.html

    So, yeah, the source engine is capable of just applying the bloom effect.

    On that, I wish you guys a wonderful evening...

    I don't get why you're worried about performance, though. HDR is a client-side video setting, and can be toggled on/off

    Yes, it is, but that's a client setting. You aren't going to force bloom onto your map.

    Uh, no.

    The biggest use of bloom in the PS2 was in Shadow of the Colossus and if you find and read the development write up for that game, you will notice that they mention the HL2:Lost Coast HDR as the example of technology that gave them the idea and that they based it on to integrate HDR into their game.

    HDR stands for High Dynamic Range, meaning that the color spectrum is adapted depending on the light you're subjected to.
    Bloom is the effect you have when there is far too much outside light compared to your current environment.

    Do you see the parallels?

    ABS: If I could force it I would. It doesn't have to be "official" bloom, it could be faked using a shader effect or an overlay. I did try a few things, but since I know people here probably tried it before, it'll save me precious time to ask.

    Drexer: no game on the PS2 has ever been released with HDR rendering. Shadow of the Colossus used FAKE HDR. It's all over the net man. You should verify your sources, because I had to do it for you, and I could've used that 1 min. for something else. :) Every game you saw showing an effect that looked like HDR, well, they were awesome enough into convincing you, Drexer, that it's HDR, but it's not.

    The machine I had when valve released Lost Coast (featuring "real" HDR) could barely run the map with HDR enabled, so, imagine our poor little PS2 with its 300mhz, 150mhz graphics card applying that effect on a full scale game?

    Nope.

    If you guys just want to prove me wrong or defy me, fine by me, freedom of speech, but it's just not going to help my cause with bloom in TF2... and it's not fun.

    I don't know why it always has to turn into a "what the hell are you talking about" "you're an idiot for wanting to do this" type of war. I guess it's in people's nature to do a little bit of flaming on a daily basis and think they're always smarter. The thing with me is that I just can't let people post false information and argue with me when they're wrong... it's in my nature. I'm sorry I had to say that, but I've had a few helpful posts at first (stickzero,capellan), then the war started based on false information. All I do is ask a question, then everyone always has to deconstruct the intention, analyse it, find the flaws and attack.
    My arguing processor is now turned off for the rest of the session. :)


    ... back to topic.

    BTW, I did compile HDR lighting on my map and it's awesome, but it's the blooming aspect of HDR that make it look nice, the eye adjusting feature is nice, but to a certain point, it's a bit distracting if the effect is too strong. I gotta tone it down, and keep the bloom mostly.
    Performance impact doesn't seem to be that bad based on primarily testing.

    Well if you're going to go with HDR but really don't want the actual HDR effect for whatever reason, I believe setting the exposure mix/max on the tonemap to the same thing (1 would be normal, I think) would effectively disable it, though it would still be compiled/processed. Also, HDR in TF2 is usually very subtle with closed bounds than in HL2. You should be fine just using it with some of the standard settings.
