Release date: Oct, 24th 2022
Please take a close look at RealFlow | Cinema 4D's list of limitations and known bugs. It is a valuable resource when you encounter problems, crashes, or difficulties:
System requirements
Cinema 4D R18, R19, R20, R21, S22, R23, S24, R25 and S26 (64 bit only)
Windows 7 (or higher) or macOS 10.9 (or higher) operating system.
CPU 64-bit Intel® or AMD® multi-core processor.
As Cinema 4D S26 cannot be changed to work either in Intel mode or M1, and the plugin is still not compatible with M1 processors, Realflow Cinema 4D S26 will only work along with our plugin on Mac computers that have Intel processors.
8 GB RAM.
100 MB disk space for installation.
Network adapter and internet access for license activation.
RealFlow | Cinema 4D supports GPU-based simulations and multi-core/multi-processor systems.
Since fluid simulations are computationally expensive and allocate large amounts of disk space we recommend Intel® i7 or Xeon systems (or comparable), 16 GB RAM (or more) and a 512 GB hard disk drive/SDD.
Features added
General
Added Cinema 4D S26 support.
Fixes
License Dialog - controls on the License file browse page are cropped (OSX only).
The installer uses the wrong folder name for the license activator. It creates the folder "License Activator" instead of "LicenseActivator" (OSX only).
The plugin starts with some python error messages (in C4D Console).
Limitations
General
RFCFD-351 - Array Tool: Parameters can't be animated for meshes.
RFCFD-517 - Initial State files created in RealFlow | Cinema 4D 1.0 are not compatible with 2.0 version due to the switch from RPC to Alembic.
Meshing
RFCFD-580 - Mesh fluid/emitter weight vertex map computation is limited to a maximum amount of 10.
Parameters
RFCFD-358 - File paths can't have unicode characters on macOS.
RFCFD-519 - Simulation steps configuration from RealFlow | Cinema 4D 1.0 scenes is reset to Auto mode when opened in version 2.0 and higher.
Rendering
RFCFD-469 - Simulation look on render may differ between multiple simulation/renders unless caching is enabled.
RFCFD-486 - Objects deformed with Rigid, Elastic and Particle Skinner only support motion blur when using the Point Cache tag.
RFCFD-499 - Particle render instances are not rendered/recognized by NVIDIA's Iray.
RFCFD-500 - Motion blur with meshes doesn't work with NVIDIA's Iray.
RFCFD-501 - Motion blur with meshes doesn't work with Maxwell Render.
Known bugs
Emitters
RFCFD-522 - Emitter ID value is not preserved on scene reopening.
Daemons
RFCFD-551 - Having two or more k Isolated daemons linked to the same fluid makes the isolation value grow as many times as the number of k Isolated linked daemons.
