Fluid Properties operator

The Fluid Properties operator allows you to save various fluid grid properties to particle custom data channels.

Fluid Node

  • Fluid input object: the fluid grid object that properties will be loaded from.

Velocity (vector)

  • Enabled: controls whether grid velocity values will be saved to a particle’s custom vector data channel.

  • Channel: the custom vector data channel in which to store the data.

Smoke (float)

  • Enabled: controls whether grid smoke values will be saved to a particle’s custom float data channel.

  • Channel: the custom float data channel in which to store the data.

Temperature (float)

  • Enabled: controls whether grid temperature values will be saved to a particle’s custom float data channel.

  • Channel: the custom float data channel in which to store the data.

Fire (float)

  • Enabled: controls whether grid fire values will be saved to a particle’s custom float data channel (FumeFX only).

  • Channel: the custom float data channel in which to store the data.

Inside (float)

  • Enabled: controls whether a grid inside/outside test will be saved to a particle’s custom float data channel.

  • Channel: the custom float data channel in which to store the data.

If a particle is inside the fluid grid, a value of ‘1’ will be saved. If a particle is outside the fluid grid, a value of ‘0’ will be saved.
