C4DtoA 3.3.6 uses Arnold 6.2.1.1 and is a minor feature release bringing improvements to the Density control in the Arnold Scatter object, exporting world space reference points and a bunch of bug fixes.

Cinema 4D S24 related issues:

  • Textures stored in the new S24 Asset Browser are not supported yet, because of a limitation in the C4D SDK. Therefore porting material libraries from the Content Browser to the new Asset Browser is not recommended.
  • Drag & drop nodes to the node editor does not work in S24, such as:
    • Drag & drop an Arnold Material to create a reference.
    • Drag & drop an object to create an object reference.
    • Drag & drop a Vertex Map to create a Vertex Map shader.
  • Ctrl + drag a shader in the node editor in S24 creates two copies instead of one. shift + drag and Shift + Alt + drag does not work.

Installation

System Requirements

  • Cinema 4D
    • R21.026 and above
    • S22.016 and above
    • R23.008 and above
    • S24.035 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 or later
  • Apple Mac models with M series chip are supported under Rosetta 2 mode
  • 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

Note, that Density now depends on the Project Scale. When you load an old scene where the Project Scale is not the default 1 cm, you have to set Points per square unit accordingly to match the look.

  • World space reference points: Reference points can now be exported in world space in the Arnold Tag of a mesh. This can be useful for instance to stick texture when using a triplanar shader in world space. (c4dtoa#2420).
