We’re back with an update for RealFlow | Cinema 4D! We didn’t just fix bugs, but added lots of nice features as well.

These functions give you more possibilities, flexibility, and control for special offers see Smarttec site. 


Have you ever made use of the mesh engine’s → vertex maps to enhance your fluid renders? If the answer is yes then you certainly know that vertex maps were limited to speed so far. But RealFlow’s → fluid and material solvers offer much more channels. With this update you now have a wider choice and we’ve added vorticity, age, and weight maps.

Furthermore we’ve introduced a new, much more intuitive and artist-friendly workflow. In previous versions you had to deal with an abstract “Scale” parameter. Instead of guessing a value it’s now possible to adjust speed, age, and vorticity precisely through → ranges – or let RealFlow | Cinema 4D do the work with the new “Auto” mode.

The icing on the cake is that you can now evaluate the changes in Cinema 4D’s viewport as you’re used to do with native Cinema 4D vertex maps. This means that you no longer have to create preview renders to see the result of your settings. Truly a huge time saver.

And to give you an impression of how these vertex maps affect your fluids we’ve created some videos for you. This clip is a side-by-side comparison of the speed, vorticity, and age channels:

In this video you can see four differently coloured fluids. Weight maps are used to create the colour mixing effects in areas where the fluids touch and interact. To create softer colour transition we have applied the new → “Smoothing Length Scale” parameter to the mesh:

Updates on the maps’ ranges will be applied automatically and displayed in the viewport, but changes on “Smoothing Length Scale” require that the meshes to be recreated.


This neat helper has been added to ease the process of adjusting daemons. RealFlow | Cinema 4D’s new → “Visualizer” is able to make forces visible and even show how they evolve and change over time. Now you have full control over daemons and instant visual feedback.

You can choose between arrows, lines, and points – and you can also display these modes as streamlets. Streamlets trace the forces over a short timespan and this results in a curved view of the force, giving you a sense of direction. One of the most interesting feature is that the “Visualizer” also shows the combined result from multiple daemons. You can decide which daemons should be visualized together with simple drag and drop. Here we have a bounded → “Noise Field”, → “Vortex”, and an animated → “Attractor”:

The “Visualizer” works with the following force-based daemons: “Attractor”, “Gravity”, “DSpline”, “Noise Field”, “Vortex”, and “Wind”. For obvious reasons you can’t visualize k daemons or the “Filter”.


Another, very important, novelty is the introduction of time offsets for cached fluids. So far you haven’t been able to shift the start and end frames of your particle and mesh sequences, for example if you wanted to synchronize them with other animated assets in your scene. In many cases it was necessary to batch rename the files or do other fancy things. But those days are over now.

  • Every → fluid, → rigid, → elastic, and → mesh container has its own node-specific “Offset”.
  • Furthermore, there’s a → global → “Frame Offset” located in the “Scene” object.
  • Both offsets influence each other: total offset = nodespecific offset + global frame offset

This way you’ll be able to shift simulation nodes freely and independently from each other, and define custom time offsets in both positive and negative directions.


All in all we’ve improved the plugin’s overall robustness. Especially → GPU simulations with a → “Filter” have been unstable under certain conditions – a thing that has been fixed.

Another important fix is that initial states will be kept from now on when you remove a simulation’s cache files. This may sound like a side note, but in fact it saves you lots of time!

And since we’ve been jumping on the “visualization train” there’s another new function: the → “Image” emitter is now capable of showing the attached image/pattern in the viewport. This will help you to identify the areas of emission. Furthermore, this emitter now supports animated textures, for example Cinema 4D’s noise types.

Not to forget the → “Fill” emitter. Now this neat little helper makes it easier to fill your objects with particles, but they can also be covered with a layer of particles.

The connection to Cinema 4D’s Thinking Particles module became much more robust, less RAM-intense, and got a new → workflow, making it easier to keep track of multiple particles/TP sources.

Our friends at → Jawset Visual Computing, the makers of TurbulenceFD, also surprised us with a neat feature: it’s no longer necessary to create Thinking Particles from RealFlow fluids in conjunction with TurbulenceFD. Aall you have to do is to apply a “TurbulenceFD” emitter to a RealFlow emitter, fluid, rigid, or elastic container directly. This improvement requires at least version v1.0 Rev 1435.

Many emitters (“Circle”, “Image”, “Square”, and “Triangle”) provide a → “Volume” parameter. This option allows you to create a defined initial volume of particles. A new handle in the emitters’ viewport gizmo lets you define this volume simply by dragging the handle, but of course you can still use numerical values as well.

Finally, we’ve added a falloff to the → “DSpline” daemon.

Of course, we’ve also improved the plugin’s overall stability, and updated to the latest Dyverso library. Experienced users will be happy to hear that the new 2.5 functions can be highlighted in Cinema 4D’s user interface.

Happy Simulating!

RealFlow for Cinema 4D – Physics simulation in a Nutshell


RealFlow for Cinema 4D – Physics simulation and awesome motion fluid effects

A few years ago we started a partnership with MAXON, the creators of Cinema 4D, and in the meantime this connection became a real friendship. You will find a MAXON booth on almost every important event, road show, or convention. And there is always a top-class lineup of international Cinema 4D artists giving workshops, showcasing their actual work, and sharing incredibly useful tips.

But it’s not just the artists, it’s also the friendly and highly-professional attitude of the entire MAXON team: they really care and they always have the best get-togethers and parties. This year, Peggy Beck and her team organized a 3-hour boat trip through the canals of Amsterdam. It must have been great, but of course I’ve missed it, because I had a rather late flight and arrived in Amsterdam when the party was almost over. I guess that’s life… 🙂

My own presentation was the last one on Sunday from 5-6 pm. Despite this late time slot I was positively surprised how many visitors dropped in to watch the workshop. Another big plus is that the live feed brings the show to everyone who’s interested, but not able to be present. Finally, the MAXON team provides an edited recording and shares all videos on their YouTube channel.

The workshop’s topic was

RealFlow | Cinema 4D 2.0 – Multi-Physics in a Nutshell

Here I’m going to show you how to create and control complex interactions between RealFlow’s different solvers and material types. Furthermore you will learn fundamental things about “Collider” and “Volume” tags, simulation settings, and the workflow for → rigid/elastic deformer.

If you’re interested in watching the recording just do it here or directly on YouTube where you will find the presentations of my fellow artists:

Having a good time together is important, but that’s just one aspect. All these shows mean that you’re present, help users with their doubts and questions, and gather feedback. It’s about connecting with real people. And it’s also about learning and sharing methods and knowledge. The feedback I get during these events is of particular importance for us and – at least I do think so – for the customer. It definitely makes a difference whether you have the opportunity to talk with someone face to face or via a communication channel. Sure, in most cases there’s no other way than using forums for social media, but the personal talk helps both sides to understand each other much better.

RealFlow | Cinema 4D Flows Directly inside Cinema 4D’s UI



RealFlow | Cinema 4D Flows Directly inside Cinema 4D’s UI

Next Limit Technologies has released a new plugin which is available now from Smarttec, RealFlow | Cinema 4D, that puts RealFlow fluid simulation software directly inside the Cinema 4D user interface. This creates a faster, simpler workflow for Cinema 4D users, without going back and forth between 3D platforms. You can use all of the native Cinema 4D tools combined with RealFlow, and connect fluid particles to MoGraph, Hair, Pyro Cluster and so on.

RealFlow | Cinema 4D produces small and medium scale fluids built on RealFlow’s Dyverso solver. The tight integration allows you to use native Cinema 4D modifiers and tools, as well as the RealFlow mesh engine, based on the OpenVDB library, and daemons to control fluids and splashes and create additional particles. You can exchange particles and meshes with RealFlow or other platforms. Results are also GPU accelerated, supporting CUDA and OpenCL.

Other specific tasks include using RealFlow nodes and Cinema 4D colliders together for particle-object interaction. C4D Cinema 4D splinescan serve as RealFlow particle paths, and Cinema 4D materials and textures as emission masks for fluid particles. Crown splashes can be created and customized on demand. You can also use RealFlow directly with Cinema 4D Mograph, converting fluid particles to thinking particles, and using particle instances and tracer objects. Configurable RealFlow WetMap Shaders will work on any Cinema 4D geometry.

The plugin is available for Cinema 4D R15 to R17 on Windows and OS X.
