.

Exponential

A value that changes at a faster and faster rate.

srcVar1

The exponent with which to calculate

offset

Offset for exponent

minVal

minVal

maxVal

resultVar

GaussianNoise

A noisy signal where values are biased towards the average.

mean

The average value around which the noise will centre

halfWidth

The distance from the average at which it's only 30% likely to occur.

minVal

maxVal

resultVar

MatrixRotate

A rotation matrix from the provided axis and angle.

axisVar

Axis of rotation, in the format [x y z]

angle

Degrees of rotation around axis.

resultVar

Todo: Output format

PlayerProximity

The distance between the entity the material is applied to and the local player.

scale

resultVar

PlayerView

The dot product of the player's view angle and the relative origin of the material's entity.

scale

resultVar

PlayerSpeed

Speed of the local player.

scale

resultVar

PlayerPosition

The local player's position.

scale

resultVar

= [x y z]

PlayerDamageTime

The number of seconds since the local player was last damaged.

scale

resultVar

EntitySpeed

The material's entity's speed.

scale

resultVar

EntityRandom

A static random number associated with the entity the material is applied to. Helpful for staggering effects that appear on multiple objects.

scale

resultVar

Texture manipulation

TextureTransform

Generates a texture transform matrix.

centerVar

Name of a variable holding the center of rotation and scaling. [Optional]

scaleVar

Name of scale variable (2D vector). [Optional]

rotateVar

Name of rotation angle variable (float). [Optional]

translateVar

Name of the translation variable (2D vector).

resultVar

Resulting value.

Empty

Used to comment out proxies. Surround a bunch of proxies with the empty proxy to cause those proxies to not operate.

TextureScroll

Returns a transform matrix or vector that will translate a texture at a given angle at a given rate.

textureScrollVar

Destination for the resulting transformation.

textureScrollRate

Rate of scroll in units per second.

textureScrollAngle

Angle of rotation to move along. (90 = up, 180 = left, etc)

ToggleTexture

Toggles a texture based on the frame number set by the attached entity.

Note:Must be attached to an entity.

toggleTextureVar

Texture to modify based on frames.

toggleTextureFrameNumVar

Variable used for frame number.

toggleShouldWrap

Whether the animation should wrap over not.

LampBeam

Modulates the material's alpha value based on angle between the beam's direction and the viewer's eye point. This is used to make the beams of volumetric light on lights fade as you look at them dead on.

Note:Must be attached to entity for angle use.

LampHalo

Modulates the material's alpha value based on angle between the beam's direction and the viewer's eye point.

Like the LampBeam proxy, but used for the halo at the beam's base.

Note:Must be attached to entity for angle use.

No return value.

AnimatedTexture

Increments frame variable

Note:animatedtextureframerate can NOT be set to a local var to be changed on the fly. It's a fixed variable, unfortunately

animatedtexturevar

Texture to increment frame for (i.e. $basetexture, $bumpmap, $normalmap (both $bumpmap and $normalmap use $bumpframe))

animatedtextureframenumvar

Frame variable to increment (i.e. $frame, $bumpframe)

animatedtextureframerate

Framerate in frames per second.

Entity integration

MaterialModify

MaterialModifyAnimated

Used in conjunction with the material_modify_control entity to configure arbitrary parameters from map I/O. Only works when the material is applied to an entity. No parameters.

WaterLOD

Coordinates water LOD values between the map's env_waterlod entity and the material's internal values.

$CHEAPWATERSTARTDISTANCE

Start distance for cheap water

Note:must be set outside of proxy block.

$CHEAPWATERENDDISTANCE

End distance for cheap water

Note:must be set outside of proxy block.

BreakableSurface

Sets the base texture to a material name held by the entity (used for switching surface material on shatter)

Note:Must be attached to a func_breakablesurface entity.

ConveyorScroll

Returns the scroll parameters for a texture used as a conveyor.

Note:Must be attached to func_conveyor entity.

textureScrollVar

Name of variable to place result in.

Note:must be a matrix or vector type variable (i.e. $baseTextureOffset).

Camo

Note:Only used by material "Dev\dev_camo.vmt".

ParticleSphereProxy

Note:Only used by material "particle\SmokeStack.vmt".

Seems to be defined in particle_proxies.cpp. Valve remark: "FIXME: Is this even needed any more?"

Shadow

Only used by material decals\rendershadow.vmt. No known parameters.

ShadowModel

Only used by material decals\rendermodelshadow.vmt. No known parameters.
