env_volumetric_fog_controller

env_volumetric_fog_controller is a point entity available in SteamVR Home, Half-Life: Alyx, and s&box.

Entity description

Controller for volumetric fogging - bounds are extents of fog irradiance volume (for indirect).

Keyvalues

Master Fog Controller (IsMaster) ([todo internal name (i)]) <boolean>

Use this as the active fog if there are more than one.

Fog strength (FogStrength) ([todo internal name (i)]) <float>

Technically the scattering value. Higher values make denser fog.

Draw distance (DrawDistance) ([todo internal name (i)]) <float>

Maximum distance to draw fog - WARNING! Changing from default will make fog blockier.

Fade-in start (FadeInStart) ([todo internal name (i)]) <float>

Distance from the eye at which fog starts to fade in.

Fade-in end (FadeInEnd) ([todo internal name (i)]) <float>

Distance from the eye at which fog finishes fading in and is at full strength.

Enable indirect lighting (IndirectEnabled) ([todo internal name (i)]) <boolean>

Indirect light strength (IndirectStrength) ([todo internal name (i)]) <float>

Indirect Lighting Dimension (IndirectVoxelDim) ([todo internal name (i)]) <choices>

Value	Description
512	Very High Resolution (512x)
256	High Resolution (256x)
128	Medium Resolution (128x)
64	Low Resolution (64x)

Fade time (FadeSpeed) ([todo internal name (i)]) <float>

Sets fade in or out time (in seconds).

Anisotropy (Anisotropy) ([todo internal name (i)]) <float>

How much the fog should get brighter when you stare directly at the light.

Fog Irradiance Texture (fogirradiancevolume) ([todo internal name (i)]) <resource:texture>

Name of the fog irradiance texture.

Source 2 Targetname

Name (targetname) <string> The targetname that other entities refer to this entity by. Entity Scripts (vscripts) <scriptlist> 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. Create Client-Only Entity (clientSideEntity) <choices> 0: No 1: Yes

Source 2 Hierarchy

Parent (parentname) <targetname> Specifies a movement parent. An entity will maintain its initial offset from its parent. Parent Model Bone/Attachment Name (parentAttachmentName) <string> The name of the bone or attachment to attach to on the entity's parent in the movement hierarchy. Use !bonemerge to use bone-merge style attachment. Model Attachment position offset (local.origin) <coordinates> Offset in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment. Model Attachment angular offset (local.angles) <angles> Angular offset in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment. Model Attachment scale (local.scales) <vector> Scale in the local space of the parent model's attachment/bone to use in hierarchy. Not used if you are not using parent attachment. Use Model Attachment Offset (useLocalOffset) <boolean> Whether to respect the specified local offset when doing the initial hierarchical attachment to its parent.

Source 2 Transform

Note:These are "Embedded Properties" which are hard-coded to appear on every entity in Hammer, regardless of their presence in any FGD files. Origin (origin) <coordinates> The world space origin of the entity. Angles (angles) <angles> The pitch, yaw, roll orientation of the entity. Scale (scales) <vector> The x, y, z scales of the entity. Not all entities can use this. Transform Locked (transformLocked) <boolean> Lock the transform at its current value, preventing the transform of the node from being modified. Only applies within Hammer. Force Hidden (force_hidden) <boolean> Visually hides the entity from the viewports. The Outliner pane will still list hidden entities. Editor Only (editorOnly) <boolean> Entity is only displayed in Hammer and will not appear in game.
