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.
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".
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.
If you want to add other secondary fluids, for example bubbles, proceed as follows:
- Set HY_Foam > Node Params > Node > Simulation to "Cache".
- Add a new "Bubble" emitter, adjust its parameters, simulate.
