RealFlow 10.1 – More Features, More Fun

We are proud to present the first patch of RealFlow 10. This update is not just a boring bug-fix and we think that many users would even call this a 10.5 version. We have added lots of interesting features, workflow enhancements, and even brand new materials for our Dyverso Multi-physics solver. Of course you will also see improved stability, tons of bugs fixed, and many other little things under RealFlow’s hood. And, yes, we have also addressed some stone-aged bugs 😉

Here’s a quick overview with the definitive highlights of RealFlow 10.1:

Dyverso Viscous Material

What’s a multi-physics solver without honey, toothpaste, caramel or heavy oil? Sure, viscosity has been around in SPH and PBD fluids for a rather long time now, but the new viscous materials rises everything to the next level: there is a dedicated material at your fingertips with much more options and specific parameters to get a convincing behavior.


Dyverso Viscoelastic Materials

Do you love to press your hand into these cool foamy mattresses and watch how they recover over time? Well, why don’t you simulate that? Dyverso’s viscoelastic solver is the perfect tool for such a project. But there’s so much more to discover, and it’s fun to play with these materials and test out its limits. Just get creative! Of course, everything can be combined with liquids or granular materials.


Dyverso Improvements

Dyverso’s PBD, SPH, and granular solvers deserved some love as well and so we added a few cool parameters:

  • Tensile strength. This parameter lets you create these neat strings with high surface tension and enhances a fluid’s borders. All in all, the behaviour of PBD and viscous/viscoelastic fluids will be much closer to what you know from the SPH solver.
  • Vorticity boost. Your fluids appear dull and turbulence vanishes too fast? With the help of this feature you will able to get a more convincing behaviour, enhance vortices and splashes. Just give it a try!
  • External pressure scale. What was formerly known as “External pressure” didn’t just got a new name, but a whole new meaning, although it has a strong technical background. The most important news for you is that it’s much easier now to control the effect of this parameter.


Filter Randomness

The “Filter” daemon has always been a great tool for the creation of foam, deleting particles on demand, removing unwanted parts of fluids, and many more. But one of its main limitations has always been the lack of randomness. This is a thing of the past and now your simulations will not only be more realistic, but you can also use it for creative things like melting effects from snow to water. Sounds fantastic, doesn’t it?


Filter by Emitter ID

Do you think that this is one of RealFlow’s typical super-technical features you’ll never understand? On the first look you might be right, but in fact it can be a life-saver. Have ever been forced to separate Dyverso or Hybrido emitters from a common domain in a post-process? If the answer is yes, you most probably failed. With this new feature you no longer have to re-simulate things, but just apply a “Filter” daemon and split your emitters. And even better: you can split emitters at simulation time, apply different materials, and combine everything with the random function to do the really cool things.


Filter Keep Source Particles

By now, the source particles have always been removed after they were shifted to another domain. Now it’s possible to keep these particles and create trails, for example. But, please do yourself a favour here, and use the “Dumb” particle type or don’t let the domains interact!


Fluid Masking

This new feature lets you cut out parts of the fluid before the simulation starts. Something that has been possible before, but only with a certain effort. You can literally model your particle volume, but without having to adjust or revisit the surrounding container object. And the best thing is that there is an automatic mode or the possibility of choosing specific objects. Furthermore you can control the size of the mask by defining an offset.


Fill Emitter Mode

Fields, solid inside, solid outside, filling and interaction objects… Filling objects with Dyverso particles was not exactly user-friendly and often lead to confusion, because you had to work with two objects: one to fill the node, and a copy for the particle interaction. Not so easy with imported objects! Now the filling process can be achieved with a single object and the new “Fill mode”. Check it out!


Alembic Parameter Panel

Alembic is a common standard and there’s no doubt about it. RealFlow supported this versatile format from the very beginning and now you can do even more. Every Alembic node has its own parameter panel where you can adjust things like animation speed, reverse animations, or adjust an offset – on a per-object base. Isn’t that great?


SD Parameter Panel

This new panel has similar options as its “Alembic” counterpart, but with limited possibilities. Anyway, you can define a per-object offset and you will always see valuable information about the file and its included nodes.


Spline Emitter Thickness

Tired of ultra thin sheets of fluid when using the Dyverso spline emitter in “Axis” mode? The “Thickness” option lets you create a thin, single-layered “curtain” or a thick stream of particles. And there is even more, because the thickness of the fluid can be controlled for every control point individually. Make more out of your splines!


Node Cloning

Cloning nodes (Ctrl/Cmd + D) is a convenient method to duplicate RealFlow items, but in the past it was very limited. Now this feature experienced a complete overhaul with neat novelties:

  • Export settings will be cloned.
  • Relations/connections to other nodes can be preserved.
  • Duplicate meshes including the attached emitters.
  • Keep hierarchies and parented nodes.
  • Clone IDOCs including their settings.
  • A new “Clone Selected Special” menu entry (“Edit”) for even more options.

Particle Skinner

The “Particle Skinner’s” major limitation has been removed and now it is possible to use it with cached particles sources as well.

And Many, Many More…

Yes, there’s even more to discover, and for a full feature list with all bug fixes and improvements please visit the “Release Notes” page of the documentation.
