- Create the object you want to use for rendering the particles.
- Scale and/or rotate it your needs, apply a material.

You can attach as many objects as you want and apply different materials as well. RealFlow | Cinema 4D will distribute the objects accordingly. Even animated objects are supported, as well as mixtures of animated and static objects.
If you want to see the objects at simulation time go to Fluid > Particles > Child Objects and disable "Render only". Be aware that disabling this option might increase simulation time.
