I was watching a tutorial on how to setup a Hybrido simulation in Realflow:
This tutorial is the first of the HYBRIDO BASIC CONCEPTS tutorials series. Here we will explain in a clear and concise manner the fundamentals of the new HYBRIDO approach to large scale liquids simulations.
This video covers the initial setup for the core fluid simulation

HYBRIDO REALFLOW 5 TUTORIAL BASIC 3

HYBRIDO REALFLOW 5 TUTORIAL BASIC 6
If I would want to recreate this whole scene, I wouldn't want to watch the tutorial all over again. That's why I wrote down each step:
How to setup a Hybrido in Realflow:

- Add -> Grid fluid -> Domain (resizable)
- Add -> Object -> Cube (resizable)
- Add -> Grid fluid -> Emitter
- Add -> Daemon -> Gravity

Click simulate.

Next the simulation needs to be cached:
- Select Grid_Fluid_Domain01
- in the Node menu, change Simulation from "Active" to "Cached".
----------------------------------------------------------------------------
Add Splash
- Make sure animation is in first frame
- Add -> Grid fluid -> Splash
- Position/Resize the Splash box to where Splash particles will be generated
- Add -> Daemon -> K Volume
- Position/Resize the K volume. Particles outside of the K volume will be destroyed

Global links/Exclusive links
- With K volume selected, remove all items from the global links menu
- From the Nodes menu, drag&drop Grid Fluid Domain to Exclusive Links
- Now drag the following items on top of the Grid Fluid Domain:
- emitter, Cube01
- Grid Fluid Emitter01
- Grid Fluid Splash01
- Gravity Deamon
- From the Nodes menu, drag&drop Grid Fluid Splash01 to Exclusive Links
- Now drag the following items on top of the Grid Fluid Splash01(in the Nodes menu):
- K Volume01 Deamon
- Gravity Deamon

Click simulate. (This could take many hours!)
Want quick results? Lower the Particles->resolution from 100 to 1, and it will go a 100 times faster.

Next the simulation needs to be cached:
- Select Grid_Fluid_Splash
- in the Node menu, change Simulation from "Active" to "Cached".

----------------------------------------------------------------------------
Add Foam
- Make sure animation is in first frame
- Add -> Grid fluid -> Foam

Global links/Exclusive links
- With Grid_Fluid_Foam01 selected, remove the Grid_Fluid_Foam item from the global links menu
- Now drag the following items on top of the Grid Fluid Domain(in the Nodes menu):
- Grid Fluid Foam
- From the Nodes menu, drag&drop Grid Fluid Foam01 to Exclusive Links
- Now drag the following items on top of the Grid Fluid Foam01:
- K Volume01 Deamon

Click simulate. (This shouldn't take long)

- in the Foam Node menu, change Simulation from "Active" to "Cached".
----------------------------------------------------------------------------
Add Mist
- Add -> Grid fluid -> Mist

Global links/Exclusive links
- With Grid_Fluid_Mist01 selected, remove the items from the global links menu
- Now drag the following items on top of the Grid Fluid Domain(in the Nodes menu):
- Grid Fluid Mist
- From the Nodes menu, drag&drop Grid Fluid Mist01 to Exclusive Links
- Now drag the following items on top of the Grid Fluid Mist01:
- Gravity Deamon
- Grid Fluid Splash01
- K Volume01 Deamon

Click simulate. (This shouldn't take long)

- in the Mist Node menu, change Simulation from "Active" to "Cached".
----------------------------------------------------------------------------
Add a mesh that will support the fluid
- Go to export -> export central
- Check the following: Grid Emitters->Grid fluid, Grid fluid->Particle cache. Click Done
- Add mesh->Grid mesh
- Click simulate. (This shouldn't take long)
----------------------------------------------------------------------------
Solve imperfections like fluttering and popping, by making the mesh smoother
- Select Gridmesh, and change Nod Params->Filter from No to Yes, Relaxation to 0.2, and steps to 64.
- Click simulate again

Regaining detail by using a displacement map
- Select Grid Fluid Domain.
- Node->Displacement->Calculate Displacement-> Change to Always, Change Quality to 2048
- Node->Displacement->Vertical scale to 0.05, Auto dimension to No, Dimension to 10, Repeat U to 3.
- Select Grid Mesh
- Node->Shader->Shader Type-> Change to Displacement
Unfortunately the last step on how to import and render the mesh/splash/foam/mist in 3D Studio Max is not there(yet?).

Didn't watch the tutorial but want to mention this anyway: do you have the required plugin(s), to import/export, installed?

I think my plugin for 3dsmax might be outdated.. Wouldn't mind to pay for it, but $200 is a bit too much.. Can't find the options I see in some youtube video's.
