Getting your first RealFlow | Cinema 4D running is a matter of seconds. Here is an example scene:

 

Check "Fill Sphere" and change "Speed" to 0.

 

 

Increasing "Resolution" creates more particles and adds detail.

 

 

A lower "Strength" decreases the amount of turbulence.

 

 

The particle simulation at frame 73.

 

If you are happy with the result, open the "Scene" object's "Cache" tab:

 

Specify a cache folder (macOS or Windows) to save the particle Alembic files.

 

Now there are two options: 1) render the → particles as objects, e.g. spheres or 2) mesh the particles. Let's proceed with the second option:

 

These settings create a rich and detailed mesh with a smooth surface.

 

Is the mesh Ok? If yes, open Scene > Cache again and click on "Cache Meshes" to save the mesh files.

Apply a material to the mesh and render with your favorite render engine.
