4.6.8.1 - Arnold for Cinema 4D

19 March 2024

C4DtoA 4.6.8.1 uses Arnold 7.2.5.3 and is a bugfix release. For the full list of features in C4DtoA 4.6.8, see the C4DtoA 4.6.8 release notes.

Installation

  • Download Arnold for Cinema 4D from your Autodesk Account. See Download Arnold for more information about downloading C4DtoA from your Autodesk Account.

  • Follow these installation instructions.

Cinema 4D Compatibility

  • R25.010 and above
  • S26.013 and above
  • 2023.0.0 and above
  • 2024.0.0 and above

Note: Known issues in the legacy Arnold Shader Network Editor since Cinema 4D S24:

  • Drag & drop nodes to the node editor does not work as expected:
    • Drag & drop an Arnold Material to create a reference. A Cinema 4D Object Operator node is created instead of an Arnold Material reference node.
    • Drag & drop an object to create an object reference. A Cinema 4D Object Operator node is created instead of an Arnold object node.
    • Drag & drop a Vertex Map to create a Vertex Map shader. A Cinema 4D Object Operator node is created instead of an Arnold 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.

Note: Adding shaders to a Node Material from python crashes Cinema 4D 2024.

Bug Fixes

  • C4DTOA-3148 - Wire Rerouter doesn't work in Arnold Node Material
  • C4DTOA-3165 - Debug shading doesn't work in Windows Cinema 4D 2024.3.1
  • C4DTOA-3173 - Black spots in the viewport when shader has bump map
  • C4DTOA-3175 - Occasional crashes when Cinema 4D is closed
  • ARNOLD-14563 - Remove 100000 limit on number of cryptomatte manifest entries
  • ARNOLD-14732 - Render hangs when distance shader is connected to displacement
  • ARNOLD-14753 - [GPU] Crash with procedurals or global light sampling with NVIDIA drivers > 550
  • ARNOLD-14770 - Moving procedural child objects doesn't update procedural bounds
  • ARNOLD-14794 - Setting array parameter with same value detected as modification

System Requirements

  • 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.
  • x86-64 CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chips are natively supported.
  • GPU rendering works on Windows and Linux only and requires an NVIDIA GPU with the Maxwell architecture or later.
  • OptiX™ denoiser requires an NVIDIA GPU with CUDA™ Compute Capability 5.0 and above.
