env_tonemap_controller

env_tonemap_controller is a point entity available in all Source games. 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.

In code, it is represented by class CEnvTonemapController, defined in env_tonemap_controller.cpp.

Flags

• 1: Master (Has priority if multiple env_tonemap_controllers exist) (New with Left 4 Dead)

Keyvalues

Base:

Classname (classname) <string>

The classname defines the type of entity. Classnames can be changed using AddOutput, which will influence how the engine deals with the entity in certain circumstances.

Name (targetname) <string>

The name that other entities refer to this entity by.

Global Entity Name (globalname) <string>

Name by which this entity is linked to another entity in a different map. When the player transitions to a new map, entities in the new map with globalnames matching entities in the previous map will have the previous map's state copied over their state.

Parent (parentname) <targetname>

Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma. Every entity can be parented, even point entities. Entities which are parented will be forced to transition to the next map, such as from a trigger_transition. Some entities which aren't intended to be parented may not function correctly. phys_constraint can be used as a workaround to parenting.

Origin (X Y Z) (origin) <coordinates>

The position of this entity's center in the world. Rotating entities typically rotate around their origin.

Pitch Yaw Roll (X Y Z) (angles) <angle>

This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.

Note:This works on brush entities, although Hammer doesn't show the new angles.

Flags (spawnflags) <integer>

Toggles features of an entity, its specific number is determined by the combination of flags added.

Response Contexts (ResponseContext) <string>

Pre-defined response system contexts for this entity. Format is key:value,key:value,.... Contexts may be filtered.

Effects (effects) <integer> !FGD

Combination of effect flags to use.

Local Time (ltime) <float> !FGD

The local time of the entity, independent of the global clock. Used mainly for physics calculations.

Next Think (nextthink) <float> !FGD

Amount of time before the entity thinks again.

Hammer ID (hammerid) <integer> !FGD

The entity's Hammer ID. Mainly used by plugins and debugging commands, such as ent_keyvalue. Can be manually assigned with the "hammerid" or "id" keyvalue. Entities spawned at run-time are not assigned any Hammer ID.

Disable for Xbox 360 (disableX360) <boolean> (New with Left 4 Dead 2) !FGD

If Yes, disables this entity on the Xbox 360 version of Source.

Entity Scripts (vscripts) <scriptlist> (New with Left 4 Dead 2)

Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions.

Script think function (thinkfunction) <string> (New with Left 4 Dead 2)

Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior. The return value (if present) will set the time until the next call. Try to avoid expensive operations in this function, as it may cause performance problems.

Lag Compensation (LagCompensate) <boolean> (New with Left 4 Dead 2) !FGD

Set to Yes to lag compensate this entity. Should be used very sparingly!

Is Automatic-Aim Target (is_autoaim_target) <boolean> (New with Counter-Strike: Global Offensive) !FGD

If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.

Inputs

SetTonemapScale  <float>

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. Not available in .

BlendTonemapScale  <string>

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. Not available in .

UseDefaultAutoExposure

Reverts to using the default tonemap auto exposure.

UseDefaultBloomScale  !FGD

Reverts to using the default bloom scale.

SetAutoExposureMin  <float>

Sets a custom tonemap auto exposure minimum.

SetAutoExposureMax  <float>

Sets a custom tonemap auto exposure maximum.

SetBloomScale  <float>

Sets a custom bloom scale.

SetBloomScaleRange  <vector> !FGD

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

Confirm:Works?

SetTonemapRate  <float>

Sets the rate for autoexposure adjustment (mat_hdr_manual_tonemap_rate).

SetBloomExponent  <float> (New with Left 4 Dead)

Sets a custom bloom exponent.

SetBloomSaturation  <float> (New with Left 4 Dead)

Sets a custom bloom saturation.

SetTonemapPercentBrightPixels  <float> (New with Left 4 Dead 2)

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

SetTonemapPercentTarget  <float> (New with Left 4 Dead 2)

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

SetTonemapMinAvgLum  <float> (New with Left 4 Dead 2)

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

Base:

Kill

Removes this entity and any entities parented to it from the world.

KillHierarchy

Functions the same as Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster than Kill.

SetParent  <string>

Move with this entity. See Entity Hierarchy (parenting).

SetParentAttachment  <string>

Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.

SetParentAttachmentMaintainOffset  <string>

As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.

ClearParent

Removes this entity from the the movement hierarchy, leaving it free to move independently.

AddOutput  <string>

Evaluates a keyvalue/output on this entity.
Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>

FireUser1 to FireUser4

Fire the OnUser outputs; see User Inputs and Outputs.

Use  !FGD

Same as a player invoking +use; may not do anything. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.

DispatchEffect  <string> !FGD

Dispatches a special effect from the entity's origin. Removed and replaced entirely by the particle system since .

DispatchResponse  <string> !FGD

Dispatches a response to the entity. See Response and Concept.

AddContext  <string>

Adds to the entity's list of response contexts. Format is <key>:<value>.

RemoveContext  <string>

Remove a context from this entity's list. The name should match the key of an existing context.

ClearContext  <string>

Removes all contexts from this entity's list.

RunScriptFile  <script> (New with Left 4 Dead 2)

Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.

RunScriptCode  <string> (New with Left 4 Dead 2)

Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console.

Bug:  In , the code is executed in the script scope of the entity that fires the output, not the one receiving the input.

Warning: Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.

CallScriptFunction  <string> (New with Left 4 Dead 2) !FGD

Execute a VScript function in the scope of the receiving entity.

SetLocalOrigin  <coordinates> (New with Alien Swarm) !FGD

Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.

SetLocalAngles  <angles> (New with Alien Swarm) !FGD

Set this entity's angles.

Outputs

Base:

OnUser1 to OnUser4

These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.

OnKilled  (Only in the Left 4 Dead series)

This output fires when the entity is killed and removed from the game.
