Usage

Effect creation

hndl = ppEffectCreate ["effect_type", priority]; hndls[] = ppEffectCreate [["effect_type0", priority0], ["effect_type1", priority1], ...];

Effect cancellation

ppEffectDestroy hndl; ppEffectDestroy [hndl0, hndl1, ..., hndlN];

Parameter setup

hndl ppEffectAdjust [par0, par1, ..., parN];

Parameter application

hndl ppEffectCommit time; [hndl0, ..., hndlN] ppEffectCommit time;

Effect permission

hndl ppEffectEnable OnOf; [hndl0, ..., hndlN] ppEffectEnable OnOf;

Check if enabled

ppEffectEnabled hndl;

Example

_hndl = ppEffectCreate ["colorCorrections", 1501]; _hndl ppEffectEnable true; _hndl ppEffectAdjust [1.0, 1.0, 0.0, [1.0, 0.1, 1.0, 0.75], [0.0, 1.0, 1.0, 1.0], [0.199, 0.587, 0.114, 0.0]]; _hndl ppEffectCommit 0; sleep 10; ppEffectDestroy _hndl;

Table of priorities

Priority defines sequence in which post effects are applied. The higher priority, the later the effect will be applied, on top of the others.

Base Priority Effect
2500 ColorInversion
2000 FilmGrain
1500 ColorCorrections
400 DynamicBlur
300 WetDistortion
200 ChromaticAberration
100 RadialBlur

FilmGrain

Title: "FilmGrain"; Base Priority: 2000

Arma 3
In Arma 3 the monochromatic parameter is numeric. Use 0 for monochrome, any other value for colour.

Number of parameters is flexible: it may be defined from 1 to 6 parameters, meaning of individual parameters is following:

Parameter Meaning Type Range Default
intensity intensity float 0..1 0.005
sharpness sharpness float 1..20 1.25

Arma 3 logo black.png1.00 Arma 3 monochromatic monochromatic integer 0, 1 0

Syntax: hndlFilmGrain ppEffectAdjust [ intensity, sharpness, grainSize, intensityX0, intensityX1, monochromatic ];

Defaults: hndlFilmGrain ppEffectAdjust [ 0.005, 1.25, 2.01, 0.75, 1.0, true // 0 for Arma 3 ];

Example: ["FilmGrain", 2000, [1, 0.15, 7, 0.2, 1.0, true]] spawn { params ["_name", "_priority", "_effect", "_handle"]; while { _handle = ppEffectCreate [_name, _priority]; _handle < 0; } do { _priority = _priority + 1; }; _handle ppEffectEnable true; _handle ppEffectAdjust _effect; _handle ppEffectCommit 5; waitUntil {ppEffectCommitted _handle}; systemChat "admire effect for a sec"; uiSleep 3; _handle ppEffectEnable false; ppEffectDestroy _handle; };

ColorInversion

Title: "ColorInversion"; Base Priority: 2500

Green Inversion of G channel (image inversion (0..no blur, 1..very blurred) float 0..1 0

Example: ["ColorInversion", 2500, [0.5, 0.5, 0.5]] spawn { params ["_name", "_priority", "_effect", "_handle"]; while { _handle = ppEffectCreate [_name, _priority]; _handle < 0 } do { _priority = _priority + 1; }; _handle ppEffectEnable true; _handle ppEffectAdjust _effect; _handle ppEffectCommit 5; waitUntil {ppEffectCommitted _handle}; systemChat "admire effect for a sec"; uiSleep 3; _handle ppEffectEnable false; ppEffectDestroy _handle; };

Advanced effects

The advanced effects are not intended to be used by the end user. They cannot be created by ppEffectCreate and their adjustments (via ppEffectAdjust) are immediate and do not require ppEffectCommit.

LightShafts

Title: "LightShafts"; Base Priority: N/A

Parameter Meaning Type Range Defaults
sunInnerRadius inner radius of the sun. 0 = no radius, 1 = full screen float 0..1 0.01
sunOuterRadius outer radius of the sun. 0 = no radius, 1 = full screen. light intensity fades out from inner to outer radius float 0..1 0.6
exposure strength of effect float 0... 0.45
decay how fast intensity of rays decays with distance float 0..1 0.89

Syntax: "LightShafts" ppEffectAdjust [sunInnerRadius, sunOuterRadius, exposure, decay];

Defaults: "LightShafts" ppEffectAdjust [0.01, 0.6, 0.45, 0.89];

blurRadius 0 = disabled blur, 1 = enabled with a radius of 2, 2 = enabled with a radius of 4. integer 0, 1, 2 1
blurSharpness the greater the sharpness parameter, the more the blur preserves edges float 0... 4
fadeSharpness fading of the AO with distance (greater value = sharper transition) float 0... 5
foregroundViewDepth distance (in meters) of foreground objects - up to this distance the depth is handled differently from the rest of the scene - to prevent huge AO kernel of foreground objects float 0... 2
backgroundViewDepth distance (in meters) of background objects - AO kernel for objects beyond this distance is computed differently float 0... 0

Syntax: "HBAOPlus" ppEffectAdjust [radius, bias, detailAO, coarseAO, powerExponent, blurRadius, blurSharpness, fadeSharpness, foregroundViewDepth, backgroundViewDepth];
