Birth PRT operator

The Birth PRT operator allows you to birth new particles that are copies of particles from a PRTLoader object.

PRT birth

  • PRT object: the input object that contains PRT particles.

  • Start/End: controls the time range in which to birth new particles.

  • New particles only: controls whether only new particles will be birthed each frame. A particle is considered new if its input ID has not been processed on a previous frame, or its age is 0.

Input channels

  • Channels: controls which PRT data channels to copy into to birthed particles.


  • Flip rotation: flips the w-component of quaternions loaded from PRT data.
