The default rendering settings are tuned to Phoenix simulations, and they might not work well for imported 3rd party cache files.

You can suppress showing of the dialogues offering presets using the inDontOfferPresets attribute of the Simulator. Setting inDontOfferPresets to 1, as shown in the image below, will disable the presets pop-up window displayed when a VDB or Field3D cache files are loaded.

Clicking the "..." button will open a menu with the following options:
Browse – Opens a dialog for choosing one of several cache file types. Phoenix can import *.f3d, *.vdb and *.prt files from other fluid simulator software products. See How to import and render simulations from FumeFX, Houdini and Maya for more information. Supported file formats are:
Reset to Default - Resets the Preview and Render Path to the default value of $(same_as_output). Help - Opens the Help page for the Input rollout of the Phoenix Simulator. |

This section contains playback options you can use for retiming a simulation after it has already finished. Using these, you can speed up, slow down or animate the motion of the simulated sequence. When retiming an existing simulation from this section without re-simulating, additional RAM might be used, and loading a new timeline frame may take longer when the frame must be obtained by creating a new one between two adjacent cache files. We will refer to the process of creating an intermediate frame from two caches as as Blending. Some of the settings in this section might require specific grid or particle channels to be saved to the cache files during simulation from the Output rollout.

In order to blend FLIP particles (e.g. Foam, Splash, etc.), enable the export of the Particle ID channel from the Output rollout of the Simulator. To blend Drag particles, enable the export of the Particle ID channel from the Particles section of the Phoenix Source used to add them into the simulation. |

The controls in this section allow you to smooth the grid channels loaded from cache files for preview and rendering. You can use this to prevent grid artifacts on meshed grid channels such as the Liquid surface, Smoke or Temperature, to remove unwanted noise in these channels, or to get smooth motion blur by smoothing the Velocity grid channel.
Threshold | inSmoothTemp[0], inSmoothSmoke[0], inSmoothUVW[0], inSmoothFuel[0], inSmoothVel[0] – If this value is 0, the entire grid will be smoothed evenly. The higher the threshold is raised, the less voxels will be affected and only the sharpest gradients will be smoothed. The highest value you could use here depends on the range of the values of the smoothed channel - for Smoke and Liquid it's usually in the [0,1] range, while for Velocity it could go as high as several hundred and for Temperature it could be over a thousand. If you set this value too high, no voxels will be smoothed at all.
...
Different applications use different channels and might have different names for them. When loading f3d/vdb files, Phoenix tries to automatically make the conversion to the supported channels. If a channel is not mapped by default, a channel can be manually set from the drop-down menu.
