Env tonemap controller

It controls the HDR tonemapping for the player. Think of it as a method of controlling the exposure of the player's eyes. Tonemapping affect all players in multiplayer. HDR settings should normally be changed through triggers, whenever transitioning between environments of different light levels (or for multiplayer, at the start of the map via logic_auto).

Keyvalues

Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

bUseNextGenBloom (bUseNextGenBloom) <choices> (only in )

• 0: NO
• 1: YES

bUseCusBloomNG_Threshold (bUseCusBloomNG_Threshold) <choices> (only in )

• 0: NO
• 1: YES

Important:Most new Black Mesa keyvalues and I/O doesn't work if this keyvalue use choice NO.

Examples

NO (Bloom old) YES (Bloom new)

fCusBloomNG_Threshold (fCusBloomNG_Threshold) <float> (only in )

Threshold for bright pass filter. Determines the influence of tonemapping; with high values, only brightest parts of frame will be bloomed.

Note:The default value from fgd is 1, which is incorrect. The default value is 0.1.

Note:A value of 0 means all pixels contribute to bloom, and is considered the most physically accurate setting.

bUseCusBloomNG_tintExponent (bUseCusBloomNG_tintExponent) <choices> (only in )

• 0: NO
• 1: YES

m_fCustomBloomNextGen_r (m_fCustomBloomNextGen_r) <float> (only in )

Determines the influence for reder tones in frame.

Note:The default value from fgd is 1, which is incorrect. The default value is 0.25.

m_fCustomBloomNextGen_g (m_fCustomBloomNextGen_g) <float> (only in )

Determines the influence for greener tones in frame.

Note:The default value from fgd is 1, which is incorrect. The default value is 0.25.

m_fCustomBloomNextGen_b (m_fCustomBloomNextGen_b) <float> (only in )

Determines the influence for bluer tones in frame.

Note:The default value from fgd is 1, which is incorrect. The default value is 0.25.

m_fCusBloomNG_exponent (m_fCusBloomNG_exponent) <float> (only in )

Determines the tightness of the bloom.

Note:The default value from fgd is 1, which is incorrect. The default value is 2.2.

Inputs

SetTonemapScale <floatRedirectInput/float> (not in )

Sets the player's tonemap scale. It should be a value between 0 and 2, where 0 is the eyes fully closed, 1 is use the unchanged autoexposure (default), and 2 is the eye fully wide open.

BlendTonemapScale <stringRedirectInput/string> (not in )

Blends from the player's current tonemap scale to a new one. The parameter syntax is as follows: <target tonemap scale> <blend duration>. For example: 0.5 10 would blend from the current tonemap scale to 0.5 over a period of 10 seconds.

UseDefaultAutoExposure

Reverts to using the default tonemap auto exposure.

UseDefaultBloomScale  !FGD

Reverts to using the default bloom scale.

SetAutoExposureMin <floatRedirectInput/float>

Sets a custom tonemap auto exposure minimum.

SetAutoExposureMax <floatRedirectInput/float>

Sets a custom tonemap auto exposure maximum.

SetBloomScale <floatRedirectInput/float>

Sets a custom bloom scale.

SetBloomScaleRange <vectorRedirectInput/Vector> !FGD

Sets a range for the bloom scale. First number is the maximum, second number is the minimum.

Bug:Broken. The code that processes this input has its formatting and source reversed.  [todo tested in ?]

SetTonemapRate <floatRedirectInput/float>

Sets the rate for autoexposure adjustment (mat_hdr_manual_tonemap_rate).

SetBloomExponent <floatRedirectInput/float> (in all games since )

Sets a custom bloom exponent.

SetBloomSaturation <floatRedirectInput/float> (in all games since )

Sets a custom bloom saturation.

SetTonemapPercentBrightPixels <floatRedirectInput/float> (only in )

Sets a target percentage of pixels to maintain above a certain brightness. (default: 1)

SetTonemapPercentTarget <floatRedirectInput/float> (only in )

Sets the brightness that the percentage of pixels defined by SetTonemapPercentBrightPixels should be kept above. (default: 45)

SetTonemapMinAvgLum <floatRedirectInput/float> (only in )

Sets custom tonemapping param (default: 3).^[Clarify]

InputSetBloomNxtGen_Threshold <floatRedirectInput/float> (only in )

Sets the influence of tonemapping; with high values, only brightest parts of frame will be bloomed.

An example of what it does.

0 (Very high values are used here for RGB) 20

InputSetBloomNxtGen_TintR <floatRedirectInput/float> (only in )

Sets the influence value for redder tones in frame.

An example of what it does.

Default. 20 (blue and green is 0 here)

InputSetBloomNxtGen_TintG <floatRedirectInput/float> (only in )

InputSetBloomNxtGen_Exponent <floatRedirectInput/float> (only in )

Sets the brightness of the bloom.
