Start Frame

  • From Simulation | rs_start_from_sim – When enabled, the Resimulation will run run from the first frame of the base simulation to the simulation End Frame or the Custom Stop Frame, depending on the options.
  • Custom | resim_startframe - Explicitly sets the Start Frame of the Resimulation. This can also be a negative number.

Stop Frame

  • From Simulation | rs_stop_from_sim – When enabled, the Resimulation will run from the base simulation Start Frame or the Custom Start Frame to the last frame of the base simulation.
  • Custom | resim_stopframe - Explicitly sets the End Frame of the Resimulation. This can also be a negative number.

Expand – Opens a floating dialog that contains the selected rollout and automatically folds the command panel rollout.

Enable Particle Resimulation | resim_resimulate_particles – Enables/disables the Particle Resimulation.

Splash and Mist | resim_splash – Specifies that the Splash and Mist will be resimulated.

The Affect Liquid parameter on the Splash and Mist rollout will be ignored when resimulating Splash, because the liquid is already simulated and cannot be changed without a full simulation.

Resimulating the Foam on Hit parameter on the Splash and Mist rollout requires Splash and Mist to be resimulated.

Foam | resim_foam – Specifies that the Foam will be resimulated.

Wetting | resim_wet – Specifies that the WetMap particles will be resimulated.

UI Text Box

The Sticky Effect setting for Wetting in the Liquid rollout will be ignored when resimulating wetting. This is because the liquid is already simulated and cannot be changed without a full simulation.

Resimulation Cache

UI Text Box
typetip

During resimulation, Phoenix reads cache files from the Base Cache Files Path, performs resimulation operations, and then saves a new cache sequence in the Output and Render Path.

For more information on how to set up resimulation paths, see the Tips and Tricks page.
