A quick script to control VFX parameters using OSC messages:
- Import OscJack (https://github.com/keijiro/OscJack/releases)
- Expose some float parameters using VFX graph's blackboard
- Add this script under your VisualEffects object
- Set OSC port, obviously.
- Add the names of the parameters to the parameters array in the inspector. (Use the EXACT same name in the VFX graph)
- Send your OSC messages from your preferred application using messages with the structure / <float_value>. Eg. "/emission_rate 10000" (emission_rate has to be the exact same name in script and blackboard).
