Automatic Linking

Connecting and linking simulation nodes is a core concept in RealFlow | 3ds Max, because it lets you define which daemons act on which fluids, or which fluids will be able to interact, for example. To ease this process, RealFlow | 3ds Max has a semi-automatic system for linking nodes.

Linking Simulation Nodes

In scenes with a fluid container

• Additional containers will be linked automatically to the ones which are currently selected
• Additional containers have to be linked manually if no container is selected.

Daemons

• will be linked automatically if the project has only one fluid container
• will be linked automatically to selected containers
• have to be linked manually if the project does not contain any fluids at the time of creation of the daemon.

Linking Objects to Fluids

In order to connect objects with fluids it is necessary to add a → "RFCollider". Each object requires its own collider, and each collider has its own "Fluid Links" field. When a collider is being added as the last simulation element it will be linked automatically to the fluid in case there is only one.

A "RFCollider" has to be linked manually if

• the project does not contain any fluids at the time of creation of the collider
• a fluid container is added to the scene after the collider has been created.

Meshes

There are two fundamental states. When the project contains

• a single fluid container the container will be linked to mesh automatically
• two or more fluids all connections have to be established manually.
