Hybrido fluids are mainly used for mid or large-scale projects and they are based on a grid and cell technology. If you want to simulate small or mid-sized volumes of water with a high level of detail we recommend using RealFlow's → Dyverso technology. Effects like splashes, foam, or bubbles can be added through Hybrido secondary fluids.

Basic Setup

In the → "Learn" section you will find a quick start tutorial about how to create a complete Hybrido scene. There you will also find guides for stopping particle emission, and more.

Setting up a Hybrido fluid scene requires just a few steps – the parameters are available under → "Node Params":

Create an object, e.g. a sphere to determine the point and volume of emission.
Add an emitter. The object will be linked to the emitter and a domain node will be created automatically.
If you want to create a stream of particle enable the emitter's "Stream" option.
Adjust the domain's parameters, e.g. "Viscosity". "Cell size" controls the number of particles.
Add a force daemon like "Gravity" or "Noise" to accelerate the particles.
Hit "Simulate".

Main Properties

Hybrido fluids always consist of a domain, an emitter, and an emission object:

The domain holds the particles and is responsible for the fluid's physical properties, as well as the number of particles ("Cell size").
The combination of emitter and object specifies the volume where the particles will be created and their initial speed.
When the first emitter is being added, a domain will be created automatically.
Fluids with different properties from multiple domains cannot interact.

Hybrido fluids have several limitations:

Hybrido is able to interact with rigid or soft bodies, but the objects do not show a correct buoyancy/floating behaviour.
Hybrido cannot interact with Dyverso, standard particles fluids, and RealWave.
Wet-dry maps cannot be created from Hybrido fluids by default.

Hybrido Secondary Fluids

Adding fluid effects like splashes, foam, or bubbles requires a certain workflow. The first part concerns the Hybrido fluid, the so-called "core fluid":

If not done already, simulate the Hybrido fluid.
Set HY_Domain > Node Params > Node > Simulation to "Cache".
Reset the scene

In the next step add a secondary fluid element, e.g. "Foam":

Create a "Foam" emitter and make your adjustments under Node Params > Foam Creation | Foam Dynamics.
Simulate.

If you want to add other secondary fluids, for example bubbles, proceed as follows:

Set HY_Foam > Node Params > Node > Simulation to "Cache".
Reset.
Add a new "Bubble" emitter, adjust its parameters, simulate.
