Post Fx in games is an interesting subject; it seems people are split between loving and hating it. On the one hand you've got the "graphics don't matter" crowd who seem to despise bloom and blur and all the rest, while another group loves the shiny.

Recently I've been creating the post fx for our drivey-crash game-thing and I discovered one of the big draws for using post-fx; it's free cool. You pay very little in performance but get heaps of cool visuals back out. When your game is already at the limit in terms of graphics and detail there's nowhere else to go, but with post-fx you can push it a little bit further without worrying about FPS. This is probably especially true for consoles which lack the power of modern GPUs.

Of course blur, bloom, HDR, light rays, all hide mistakes, low resolution textures and simple geometry as well; post-fx is the video-game equivalent of the night scene with rain in films.

To demonstrate I'll take an ordinary shot of the inside of a warehouse which looks alright but not special using no post:

And then drown it in post-fx:

It's an extreme example; it looks pretty ridiculous and it's difficult to see where you're actually driving, but it sure does look cool.

Effects can also be used to draw attention to areas as well though, like in the following shot the depth of field makes us look to the open area between the building we're in and the background warehouses. A slight softness with depth of field or motion blur can also help draw you in and increase the immersion. Real life doesn't have sharp geometry and perfect focus.

Free cool is my guess as to why post-fx are so prevalent in modern games. Creating a realistic environment in a game is much more difficult than making a cool environment.

Don't worry though, I'm aiming for "eye realism" for the main look of the game, here's a shot of how things look at the moment:

    Would it be possible to edit this effect? If so, I would make it less blue. It would work in a snowy / cold map though, add to the feel.

    Currently you can edit it, but it's probably not final at the moment so I can't say for sure what it's going to be like on release.

    Perhaps it would be cool if the map creators could have a section in their maps code which allows them to create their own over ride settings. This would allow more creative freedom in map creation and if the map creator doesn't know or doesn't want to do this then they can leave it blank and the game will resort to default.

    Sure this would result in some super ugly stuff, but just imagine how well this could work with more saturation and bloom on tropical maps and other similar effects. This sort of thing would have made dega's futuro track (for ror) look amazing.

    Wow, the graphics are really shaping up. The eye-realistic so to speak does just that, it looks awesome Hutch

    Graphics does matter. But too much blur and bloom, and dof, and lens flare, etc. Doesn't make good graphics. They make bad graphics look cool, until you realize its actually crap.

    They make mistakes better. And I hope you can mess whith bloom, blur and HDR so it makes everyone happy. I have never seen a game where you can change that by opening something in wordpad and changing the shader buffer or something like
    Code:
    /blur 3.0 ;(default=4.0)

    Hi, I know this is old but with the (hopeful) progress I had other questions.

    As I said above I would like an in game editor for all the shiny, but I would also like to go deeper. The graphics actually interest me more than anything else in the game business in general.
    This being a more "connected to the community" game I am hoping to have the entire shader code be editable, much like sonic ethers shaders for minecraft. Have your editable values, but also be able to write your own experimental shaders. Another thing I hope for is to not just have a low-medium-high type thing in game, but have the ability to change the level of HDR and bloom or bloom, blur and the white balence of the HDR in game, kind of like the outeraa engine.
    Thoughts?

    Im hoping that those sorts of things will be left up to the map makers. That way you could get some really awesome tron and child of eden (rez) style maps.
    This would also mean that if you are able to edit the maps you can adjust to your liking.

    Wow, 3 minute reply. Lurk much?
    But I like that idea, but I also want to be able to change it all, really down to the color and the amount of light that bounces off the objects. The only way I know to show what I mean is to download sonic ethers shaders and go into the .vsh and .fsh files with notepad ++. Imagine being able to change the shader code of the entire game to fit your pc's power. I also like the more technical in-game options like being able to change the shadow map resolutions and stuff. Outeraa is a prime example of that.

    It should be an option in the game, to turn it on/off and to use a slider to change the amounts and certain effects
