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.

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.

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.
