Liquid simulations are displayed using the Particle Preview by default. You can also enable the Show Mesh mode, to override the Particle Preview and show the liquid as a mesh.
The Particle Preview controls let you specify which particle types to previewsection lets you control the visibility of different Particle Types, and manage their preview color. For example, you could preview only the Splash and Foam particles.
...
In addition, you can preview the simulation’s Velocity, to to see how Phoenix forces or standard 3ds Max forces affect the simulation.

Particle Preview
...
UI Text Box | ||
---|---|---|
| ||
The parameters here control the visualization of Particle Types generated by the Simulator. Phoenix can only preview the Particle Types present in the cache file for the current frame. |

You can specify a Particle Channel to use as a basis for adjusting the particle preview color, using the Scale Color By option. For example, you could set the Scale Color By option to the Speed particle channel, so that the faster the particles move, the whiter they appear in the preview. You can find more info on Particle Channels from the Particle Channel Ranges page. |

Voxel Preview
...

The Voxel Preview displays the Grid Channel content of each cell. Phoenix can only preview the channels present in the cache file for the current frame. All enabled channels are drawn if their content is between the corresponding thresholds. To see the list of available channels and their ranges for an input sim cache, go to the Cache File Content section of the Simulation rollout. You can also find more info on the Grid Channel Ranges page. |

Note that you can also specify the Voxel Preview value range for any Grid Channel, if you disable the Auto Range option. For example, you could enable only Viscosity, and specify the range to be between 0.5 and 1.0, so that you can see where the liquid is more viscous. Grid Viscosity Channel values that are below 0.5, or above 1.0, would not appear in the preview at all. |
