C4DtoA 3.3.1 uses Arnold 6.2.0.1 and is a minor feature release bringing imager fixes, support for implicit volumes, displaying ACES output color space in the Picture Viewer, using GPU in single frame Team Render and more.

Installation

System Requirements

  • Cinema 4D
    • R20.057 and above
    • R21.026 and above
    • S22.016 and above
    • R23.008 and above

  • Windows 10 or later, with the Visual Studio 2019 redistributable.
  • Linux with at least glibc 2.17 and libstdc++ 4.8.5 (gcc 4.8.5). This is equivalent to RHEL/CentOS 7.
  • macOS 10.13 to 10.15. Note that macOS 11 Big Sur is not certified.
  • CPUs need to support the SSE4.1 instruction set.
  • GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ampere, Turing, Volta, Pascal, or Maxwell architecture. We recommend using the 460.39 or higher drivers on Linux and 461.40 (Quadro), 461.40 (GeForce), or higher on Windows. See Getting Started with Arnold GPU for more information.
  • Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above.

Enhancements

Using the built-in Cinema 4D color space you can render to the Picture Viewer and then you can select to save to an 8-bit sRGB or 32-bit linear image. When a custom output color space is used however, the process is different and you must set the Output Color Space before rendering depending on your preferred output:

  • If you want to save to an 8-bit image, the Output Color Space has to be set to the custom color space (e.g. Output - sRGB). 
  • If you want to save to a 32-bit linear image, the Output Color Space has to be set to <disabled>

Bug Fixes

  • c4dtoa#2314 Cannot bake AOVs to texture

  • core#10355 Do not warn about loading non-Arnold Yeti libraries
  • core#10334 [GPU] Deleting layers in imager_light_mixer cause GPU crashes and frame corruption
  • core#10345 [GPU] Stack overflow when using wireframe with many sided polygons
  • core#10306 [Imagers] imager_denoiser_noice creates black layers for AOVs not matching layer_selection
  • core#10269 [Imagers] Slowdown when doing frequent imager updates
  • core#7216 [OSL] Wrong hit distance returned after trace() call
  • core#10316 Rare IPR hang
  • core#4530 Reset texture cache stats after every render
  • core#4845 Support detection of Windows version > 8.0
  • usd#654 Transform is not synced for the points primitive


There's a known bug in Cinema 4D R23.008, that plugins are not loaded automatically in Team Render Client and Commandline render. The plugins folder (e.g. c:\Program Files\Maxon Cinema 4D R23\plugins) has to be added manually.


In Team Render Client go to File -> Preferences... -> Plugins -> Search Paths -> Add Folder...


For Commandline, specify the g_additionalModulePath environment variable.
