Animate parameter
animate_parameterAutomate node parameter animation in TouchDesigner by binding targets to an LFO CHOP, cycling values between min and max with selected waveforms.
Instructions
Drive one or more node parameters over time with an LFO (sine/triangle/ramp/square/pulse/random). Creates an LFO CHOP and binds each target so it oscillates between min and max with the given period — movement without manual keyframing.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| max | No | High end of the value sweep. | |
| min | No | Low end of the value sweep. | |
| name | No | Name for the LFO CHOP. | lfo_anim |
| targets | Yes | Parameters to animate, each written as 'nodePath.parName' (e.g. '/project1/sys/blur1.size'). Each is switched to expression mode so it tracks the oscillator live. | |
| waveform | No | Oscillator shape. Every waveform sweeps the full min–max range. | sine |
| container_path | No | Where to create the LFO CHOP; defaults to the first target's parent network. | |
| period_seconds | No | Seconds for one full cycle (lower = faster). |
