Node Reference

Output Nodes

Terminal nodes that produce lighting output for the compositing system -- dimmer, color, position, strobe, and speed.

Output Nodes

Apply nodes are the terminal nodes of a graph. They have no wired outputs. Instead, they generate LayerTimeSeries entries that are collected at the end of graph execution and sent to the compositing system.


Apply Dimmer

FieldValue
Type IDapply_dimmer
CategoryOutput
DescriptionSets fixture dimmer/intensity channel.

Inputs

PortTypeRequired
selectionSelectionYes
signalSignal (C >= 1)Yes

Outputs

None.

Parameters

None.

Behavior

  • Uses the first channel (C=0) as the dimmer value.
  • Broadcasts N dimension to match selection size (e.g., a single-N signal applies the same value to all fixtures).
  • Dimmer values are typically 0.0 (off) to 1.0 (full intensity).

Apply Color

FieldValue
Type IDapply_color
CategoryOutput
DescriptionSets fixture color channels (RGB or RGBA).

Inputs

PortTypeRequired
selectionSelectionYes
signalSignal (C >= 3)Yes

Outputs

None.

Parameters

None.

Behavior

  • If C=3, treats the signal as RGB.
  • If C=4, the fourth channel is alpha (tint strength).
  • Broadcasts N and T dimensions to match the selection and time range.

Apply Position

FieldValue
Type IDapply_position
CategoryOutput
DescriptionSets moving light pan/tilt angles.

Inputs

PortTypeRequired
selectionSelectionYes
panSignal (degrees)No
tiltSignal (degrees)No

Outputs

None.

Parameters

None.

Behavior

  • Disconnected pan or tilt inputs produce NaN, which tells the compositing system to hold the previous position.
  • Angles are absolute (not relative to current position).

Apply Strobe

FieldValue
Type IDapply_strobe
CategoryOutput
DescriptionSets fixture strobe/shutter effect.

Inputs

PortTypeRequired
selectionSelectionYes
signalSignal (C >= 1)Yes

Outputs

None.

Parameters

None.

Behavior

  • Value 0.0 = strobe off (open shutter).
  • Value 1.0 = maximum strobe rate.
  • Intermediate values scale the strobe speed linearly.

Apply Speed

FieldValue
Type IDapply_speed
CategoryOutput
DescriptionSets gobo/pattern rotation speed (binary: frozen or fast).

Inputs

PortTypeRequired
selectionSelectionYes
speedSignal (C >= 1)Yes

Outputs

None.

Parameters

None.

Behavior

  • Thresholded output: speed > 0.5 produces 1.0 (fast rotation), otherwise 0.0 (frozen).
  • Binary behavior simplifies control -- there is no gradual speed adjustment.
