General

This rollout is used to enable/configure the simulator for resimulation. As opposed to the normal simulation, the resimulation is done on top of an existing cache with exported velocity field.


Note This rollout contains only the most common attributes that can be used when in resimulation mode. If you need more complicated setup (i.e. change the SPF limits, dynamics, rendering, etc.), you can create a second simulator just for resimulating the content of the base one, and override as many parameters as you wish.

Attributes

Interaction

Resimulate resimulate - enable/disable the resimulation mode. When in this mode, all normal parameters/actions affect the resimulation.


Cache Waiting rsWaitMode - Wait if the input cache file is not yet available. This can be used if another instance of Maya is simulating the base cache at the same time (on the same or other computer).


Input Simulation Path rsInput - specify the input simulation cache on top of which to resimulate. The bottom control shows the resolver path.


Output Simulation Path rsOuptut - specify the path for the output cache files. See Output Path for details. The bottom control shows the resolver path.


Warning! PhoenixFD will not prevent you from overriding the original input cache! If you don't have enough disk space, it's a valid option to do so.

Clear phxfdClearCache $node 1 - deletes the output cache files.


Affect rsAffect - specify which part of the simulator to be affected during the resimulation.


Amplify Resolution rsResAmplify - allows the grid resolution to be increased a specified amount of times. 0 means "no change", 1 means "x2", 2 means "x3", etc. Non integer values can also be entered, however they are slightly slower to calculate. Only available when the grid is affected.


Amplify Method rsResAmplifyMethod - when the grid resolution is increased, specify which method to use to recover the velocity.


Wavelet Strength waveletStrength - specify the strength of the wavelet turbulence.


Wavelet Cutoff waveletCutoff - turbulence with smaller amplitude will be cut off (i.e. for speed).


Conservation Quality rsConservQ - specify the conservation quality when calculating the subframes. Generally this can be a couple of times lower than the conservation quality used when simulating the input simulator. Value of 0, will still preserve the general flow of the fluid, but will produce lower diffusion and will look more like particles than fine smoke.


Temporary Channels rsTempChannels - specify the channels that are used just for resimulation and must not be exported to the resimulation output cache. For example when you are doing wavelet turbulence, you will want to remove the UVW/Wavelet and Velocity channel from the final simulation.
