Initialize and Freeze All Particles
Add the script to Simulation Flow (Ctrl/Cmd + F2) > SimulationPre.
The script freezes a particle volume at the beginning of the simulation (only works with standard particle fluids only):
| Code Block | ||
|---|---|---|
| ||
# Initialize the emitter by freezing its particles before the simulation starts # Get the standard particle emitter "Circle01" and its particles emitter = scene.get_PB_Emitter("Circle01") particles = emitter.getParticles() # Loop through all particles and freeze their motion for particle in particles: particle.freeze() |
...
Unfreeze Particles
Add the script to Simulation Flow (Ctrl/Cmd + F2) > FramesPre or StepsPre.
The script unfreezes a particle (only works with standard particle fluids) when an animated object (here: "Sphere01") is 0.75 m or less away from the particle:
| Code Block | ||
|---|---|---|
| ||
# Get the standard particle emitter "Circle01" and its particles # Define a "melting" object ("Sphere01") and a threshold emitter = scene.get_PB_Emitter("Circle01") particles = emitter.getParticles() unfreezeObject = scene.getObject("Sphere01") |
...
distThreshold = 0.75 # Loop through all particles for particle in particles: # Get the distance between the current particle and "Sphere01" particlePosition = particle.getPosition() objectPosition = unfreezeObject.getParameter("Position") particleObjectDistance = particlePosition.distance(objectPosition) # If the distance is smaller than or equal to "distThreshold" the particle will be released if (particleObjectDistance <= |
...
distThreshold): particle.unfreeze() |
