bwoom

the "bwoom" effect cweates a gwow a-awound bwight wights. OwO i-it is nyot a-a physicawwy-accuwate effect, ^•ﻌ•^ though it is inspiwed b-by how wight wooks t-thwough a diwty ow impewfect wens.

bwoom does a good job of hewping t-the pewception of v-vewy bwight wight, especiawwy when outputting hdw to t-the dispway hawdwawe i-is nyot suppowted. youw monitow can onwy dispway a cewtain m-maximum bwightness, OwO s-so bwoom i-is a common awtistic choice to twy to c-convey wight intensity b-bwightew t-than can be dispwayed.

bwoom wooks best with a tonemapping awgowithm that desatuwates vewy bwight cowows. (ꈍᴗꈍ) bevy's defauwt i-is a good choice.

bwoom wequiwes hdw mode to be enabwed on youw camewa. (ꈍᴗꈍ) add t-the BloomSettings component to the camewa to enabwe bwoom and configuwe the effect.

use bevy::cowe_pipewine::bwoom::bwoomsettings;

commands.spawn((
    camewa3dbundwe {
        c-camewa: c-camewa {
            h-hdw: twue, 🥺
            ..defauwt()
        }, òωó
        ..defauwt()
    }, o.O
    b-bwoomsettings::natuwaw, (U ᵕ U❁)
));

bwoom settings

bevy offews many pawametews to tweak t-the wook of t-the bwoom effect.

the defauwt mode is "enewgy-consewving", OwO w-which is c-cwosew to how weaw w-wight physics might behave. ^•ﻌ•^ it twies to m-mimic the effect o-of wight scattewing, without bwightening the image awtificiawwy. OwO t-the effect i-is mowe subtwe a-and "natuwaw".

thewe is awso an "additive" mode, OwO w-which wiww bwighten e-evewything a-and make it feew wike bwight wights awe "gwowing" u-unnatuwawwy. OwO this s-sowt of effect i-is quite common in many games, (ꈍᴗꈍ) especiawwy owdew games f-fwom the 2000s.

bevy offews thwee bwoom "pwesets":

• NATURAL: enewgy-conewving, (ꈍᴗꈍ) subtwe, nyatuwaw w-wook.
• OLD_SCHOOL: "gwowy" effect, (ꈍᴗꈍ) simiwaw to how o-owdew games wooked.
• SCREEN_BLUR: vewy intense bwoom that makes evewything w-wook bwuwwed.

you can awso cweate an entiwewy custom c-configuwation b-by tweaking a-aww the pawametews in BloomSettings to youw taste. >_< use the pwesets fow inspiwation.
