With this option it is possible to activate export functionality for Hybrido's secondary elements, e.g. splashes. These nodes behave like traditional particle emitters, and they can interact with other emitters, daemons and objects in the same way. RealFlow supports these file/export formats:
...
| Extension | File type |
|---|---|
| RPC | RealFlow particle cache |
| BIN | Particle cache |
| ABC | Alembic particle sequence |
| ASS | Arnold scene source |
| PXY | Particle proxy format |
| PRT | Krakatoa's™ native file format |
| PD | Particle sequence |
| ASC | Particle sequence |
| FTC | Foam texture cache |

The Alembic format is relatively new, but quickly found its way into the most common 3D platforms. One of the most important advantages is that Alembic is a hierarchical format. This means that the original structure of the source objects will be preserved, e.g. groups, links, connections etc. The Alembic format is also available for all major operating systems and does not require any extra plug-ins or exchange tools to load and process the data. RealFlow's Alembic particle files support all relevant magnitudes and properties: simply expand the Alembic tree and make your selection. RealFlow's implementation of the Alembic format supports 10 different compression levels from 0 to 9. A higher value indicates a stronger compression. As usual, the compression requires some time and so the saving process becomes slower, but it is more resource-friendly. You can also choose which particle channels you want to export.
Arnold Scene Source (.ass)

Particle proxy (.pxy)
Proxy formats are perfectly suited to saving large amounts of particle data, but not all of the information is stored on these files. Only a particle’s ID, position and velocity are considered. Depending on the adjusted quality level, particles are left out during storage. There are five quality levels (best – draft) to choose from. They can be seen/adjusted with a double-click on the “Best” option (to the right) to the export resource's name. The PXY format is only internally supported by RealFlow.

If you are simulating foam from a texture this file is needed: it makes sure that you can resume your simulation.
Foam texture (*)
The “Foam” emitter allows you to calculate maps from the particles. When the foam map feature is enabled please do not forget to activate this resource, because otherwise the maps will not be saved. You can choose from various image file formats with a double-click on the “tif” entry in the “Options” column.
