System Requirements

  • Windows 8.1 or later
  • Cinema 4D integration requires R20 or later
  • GPU simulation requires an Nvidia GPU with CUDA CC 3.5 or later (see
  • Redshift integration in standalone app requires Redshift v3.0.36.
    Redshift in C4D is unaffected by this requirement.


  • [Advect] Fixed: clipping was incorrect in some cases.
  • [Advect] Support advection of non-velocity vector grids (e.g. RGB)
  • [Advect] Allow disabling of velocity advection.
  • [C4D] Added support for R24.
  • [CodeEditor] Tree selection did not update in some cases when switching files.
  • [CodeEditor] List only explicitly opened files io. all loaded files.
  • [DFG] Node error messages were reset too early and logged ambiguously in some cases.
  • [Examples] Fixed several broken example scenes.
  • [GraphEditor] Connection visibility was not set correctly for connections crossing tree levels.
  • [Installer] Install C4D plugins in C4D app folder io. user-local.
  • [ProjectVelocity] Added Dilation Padding parameter.
  • [UI][C4D] Fixed: cycle elements did not translate selection correctly.
  • [UI] Fixed: removing connections incorrectly re-positioned node in some cases.
  • [UI] Fixed: removing connections via selection parameter lists did not work in some cases.
  • [VolumeMaterial] Fixed incorrect clipping of emission field.
