Hybrido Questions

Next Limit promises a speed boost of 2x in RealFlow 10, but in my tests it's even slower. Why?

The speed improvement is only noticeable in large simulations. A very good benchmark is the following scene Demo scenes > Hybrido > Hybrido Uboat.

With this project we got a speed bump of exactly 2x on our reference system (Intel Core i7-2600K @ 3.40 GHz):

  • The fact that you see increasing simulation times with small Hybrido projects is that our large scale fluid technology is optimized for huge amounts of particles. 
  • Furthermore, Hybrido is based on sparse OpenVDB grids and with small amounts of particles it takes some time to write these files.
  • In previous versions we provided the possibility of writing very fast, but memory-inefficient, dense grids. This option is no longer available.
Is it possible to mix Hybrido fluids with Dyverso or standard particle fluids?

No. They are completely different technologies.

What is the Hybrido domain?

This is the place where the so-called core-fluid simulation takes place – the main body of water. In further steps the Hybrido secondary fluids (e.g. splash, foam, mist) are generated.

The domains holds the simulation's particles, while the emitter specifies the point of particle creation.

Can multiple Hybrido domains interact?

No.

Do the "k" daemons affect the Hybrido domain?

Yes.

Does Hybrido support (variable) viscosity?

Yes.

How do I work with Hybrido and Hybrido secondary fluids.

Complete workflow descriptions for every Hybrido simulation node can be found in the manual's → "Learn" section.

Why refuses the "Splash" emitter to create particles?

The "Splash" emitter is bounded by default and in many cases you have to resize the emitter's bounding box to enclose the entire Hybrido core fluid.

You should also make sure that the "Splash" emitter is connected to the Hybrido domain in the → "Relationship Editor".

For a workflow description read the → "Splashes" chapter.

Why refuses the "Foam" emitter to create particles?

You should make sure that the "Splash" emitter is connected to the Hybrido domain in the → "Relationship Editor".

Please also check that the foam emitter's bounding box encloses the Hybrido core fluid.

For a workflow description read the → "Foam" chapter.

Is Hybrido GPU-accelerated?

Yes, but within very narrow limits. For more information read the → "GPU" chapter.
