New Features

Here is a brief overview of what is new in RealFlow 10.0 and 10.1


  • New viscous and viscoelastic materials (10.1).

  • Dyverso Multi-Physics solver. All materials are managed under the same solver framework.

  • The "Bitmap" emitter now shows the bitmap used for emission in the viewport.

  • Huge speed improvement in calculating the volume of interacting objects.

  • New parameter "Continuous Collision Detection" for the Dyverso solver. Thin objects are seen by the solver even when the time step is very small.

  • Dyverso solver speed and memory improvements:
    GPU 3-8x (over CPU)
    GPU CUDA 3x (over RealFlow 2015)
    GPU OpenCL 3x (over RealFlow 2015)
    CPU 2x (over RealFlow 2015)


  • Hybrido solver speed improvements: up to → 2x faster with large scenes

  • Hybrido solver memory improvements. Now the the grid creation mode has been removed as it is always sparse. This means a huge improvement in memory consumption compared to scenes where the "Dense" mode was used.

  • New, more realistic, way of generating Hybrido foam.

  • "Time Scale" option now affects all Hybrido secondary fluid emitters.

  • Huge speed improvement in calculating the volumes of interacting objects.

  • Completely OpenVDB-based workflow.

GUI and Workflow

  • New "Alembic" and "SD" panels for animation control (10.1).

  • "Skinner" daemon can be used with cached particle sources (10.1)

  • New, more, and better cloning options (10.1).

  • "Allow faster than FPS playback" tries to maintain the adjusted FPS rate during playback - or not (10.1).

  • Video output format has moved from AVI and QuickTime to MP4 (10.1).

  • New project management window with direct access to demo scenes and extended scene information.

  • New "Export" panel for nodes. Now it is possible to change the export options directly in the node export panel without going through the "Export Central" window.

  • Improvements on the parameters panel: a group of related parameters can be collapsed/expanded for better readability.

  • New "Pack and Go" tool. Create a zip file that contains all the external files needed by your scene. Advanced options to manage cache files and much more.

  • New functionality for parenting nodes in the "Nodes" panel.

  • Better support for 4K monitors.

  • New "Save incremental" option to save different versions of the same scene with different file names automatically.

  • Environment variables can now be used in many different parts of RealFlow where text is required. For instance in the preferences window for setting standard folders.

  • Possibility of disabling the saving of standard particle fluids and RealWave surfaces in the project file. This will speed up loading and exchanging project files.

  • New preview function with project thumbnails and descriptions.

Other Improvements and Novelties

  • New "Filter" daemon options "randomization", "filter by Id", and "keep source particles" (10.1).

  • Thickness parameter for the Dyverso “Spline" emitter (10.1).

  • New demo projects shipping with RealFlow 10.1 featuring granular, viscous, viscoelastic materials, and more.

  • New option in the "k Volume" daemon for using arbitrary objects to delete particles.

  • Removed bounded parameters in some daemons where the same functionality can be achieved using the falloff option.

  • The "Quick Access Tool" lets you browse through RealFlow's commands and tools by entering a name or a part of it.

  • Daemons with the falloff option now accept objects to calculate the falloff's shape.

  • A new "Particle Skinner" daemon lets you transfer particle positions to an object's vertices – great for Dyverso's new "Rigid" and "Elastic" materials.

  • Alembic files use the Ogawa backend; MD5 is still available on demand in RealFlow's preferences.

  • RealFlow 10's Alembic files are now compatible with Clarisse iFX.

  • We have changed our version scheme and went back to our former standard enumeration. The new version number is RealFlow 10 instead of RealFlow 2016.

  • New "Group" object. Now, group containers are objects and can be scaled, rotated and positioned as any other object. A group's children will be transformed as well.

  • Many, many bug fixes.
