... Export Meshes Correctly?

If you want to use channel data then this step is of particular importance, because in RealFlow's “Export Central” you will finally define which channels will be added to the meshes. First, open

RealFlow menu > Export > Export Central

and look for “PARTICLE MESHES” or “HYBRIDO MESHES” depending on the mesh type. Expand it and enable the “Mesh sequence (.md)” option. When you open the MD branch you will see checkboxes for all channels.

Export options for particle and Hybrido meshes - the "MD" resource is expanded.

Please leave the “Mesh cache (.bin)” resource active, because it is RealFlow's cache format. Without this file type, the meshes will no longer appear in RealFlow's viewport, and it is impossible to create previews.

Since the workflow is slightly different for Hybrido and particle meshes, the descriptions are split.

Hybrido Meshes

To exclude a channel from the mesh all you have to do is to deactivate its checkbox. Click on “Done” and build the meshes.

Particle Meshes

Of course, only those channels you have activated in the mesh node's “Particle Channels” panel will be equipped with data. It is possible to activate different channels as well here, but they will not contain any information. The best idea is to keep the mesh's panel open, and activate the export resources accordingly. Click on “Done” and create the meshes for the simulation range.
