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 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.
Scattering and Random Instances
The "Random" parameters turn RealFlow | Cinema 4D into an easy-to-use scatterer. This way it is possible to randomize the render instances in terms of position, rotation, and scale. This is, for example, great for sand, gravel, or stony grounds.
