Material modify control

Template:Base point It is used to modify arbitrary material properties in response to I/O events.

For the entity to work, its target material must have the MaterialModify or MaterialModifyAnimated proxy installed, and must be applied to an entity.

Confirm:If the material_modify_control entity is parented to another entity, it will only affect the material where it appears on that parent. Otherwise, it will affect all entities.

Keyvalues

Material to modify <string>

Path to the VMT file you want to modify.

Material variable to modify <string>

Name of the shader parameter you want to modify.

Parentname:

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.

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.

Inputs

SetMaterialVar <string>

Sets the chosen material parameter to the specified value

SetMaterialVarToCurrentTime

Sets the chosen variable to the current server time

StartAnimSequence <Frame Start> <Frame End> <Frame Rate> <Loop>

Force an animated material with the MaterialModifyAnimated proxy to play a set of animation frames. "Loop" should be 1 or 0.

Tip:Setting "Frame End" to -1 uses the last frame of the texture.

StartFloatLerp <Start Value> <End Value> <Transition Time> <Loop>

Makes a material with the MaterialModifyAnimated proxy smoothly interpolate the chosen material variable between two floating point values. "Loop" should be 1 or 0.

Parentname:

SetParent <stringRedirectInput/string>

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

SetParentAttachment <stringRedirectInput/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 <stringRedirectInput/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.
