Although rigids and elastics are represented through particles, they are not categorized as fluids, but as deformer:
- Both types apply vertex deformation and velocity from particles to attached objects.
- In order to achieve better results we recommend adding a "Volume" tag to the objects you want to turn into rigids/elastics. Do not apply "Collider" tags.
- The rigid/elastic deformer provide a "Resolution" parameter to create more or less particles.
- The objects' number of polygons also plays an important role: with high-res objects you normally get better results, e.g. fine wrinkles with cloth-like elastics.
Interactions With Liquids
Rigid and elastic particles are able to interact with all types of liquids, granular particles, force-based daemons, and objects with → "Collider" tags. Interactions between other rigid/elastics are supported as well. Mind the appropriate → "Links" field to establish the interactions.
"Liquid - SPH" is not supported and won't see any interaction.
How to Apply Rigid & Elastic
To make RealFlow | Cinema 4D's rigid and elastic deformer work correctly a certain hierarchy is required:
Here, all spheres will be controlled by a common "Elastic" object. For "Rigid" the setup is exactly the the same.
In the example, every sphere has its own "Elastic" deformer.
Using MoGraph Cloner
It is possible to create instances from a base object through a MoGraph cloner and turn these objects into rigid and elastics. Again, a certain hierarchy has to be maintained:
The deformer can be above or below the "Cloner" node – the result will be the same.

Particle Skinner
This helper allows you to transfer particle velocity and position data to objects. The "Particle Skinner' is already implemented in the "Rigid" and "Elastic" deformer and therefore not necessary anymore.
