If you went through "Foam with Standard Particles" tutorial you might have been missing one thing: mesh creation. In this workshop you will learn how to mesh the results from this lesson.

The mesh node now has an alias of “Square01” attached.

Open the “PARTICLE MESHES” branch. There you will find several file formats to choose from.
BIN is the standard format and supports only a few basic channels.
ABC (Alembic) can store the entire range of channels.
MD provides the most sophisticated method, because here you can also decide which channels you want to include.
Enable “Mesh sequence (.md)” and leave “Mesh cache (.bin)” activated, because it is required by RealFlow.
Uncheck the unused channels, but leave “normal” and “texture” active in any case.
Click on “Done”.
Build Mesh Sequence
Now, the mesh sequence can be created:
...
This action can be stopped with the Esc key, but it might take a short while until the process is interrupted, because the current mesh will be finished first. All files will be written to the project's “mesh” folder.
You will see a warning in the "Messages" panel, telling you that RealFlow did not find any meshes. This warning can be ignored, because during the mesh creation process RealFlow is playing back the simulation and looks for already existing mesh files.
