4.5.1.1 - Arnold for Cinema4d

03 Feb 2023

C4DtoA 4.5.1.1 uses Arnold 7.1.4.2 and is a bugfix release.

Installation

  • Download the Arnold for Cinema4D plugin
  • Follow these installation instructions.

Cinema 4D Compatibility

  • S24.111 and above
  • R25.010 and above
  • S26.013 and above
  • 2023.0.0 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.

Bug Fixes

  • C4DTOA-2902 - Attribute field is missing from user data shader UI in Cinema 4D 2023.1

  • ARNOLD-8417 - Memory leaks when using kick -turn

  • ARNOLD-11020 - Quad light color not automatically updated in IPR

  • ARNOLD-12083 - Remove unused -gpu_cache_dir kick flag

  • ARNOLD-12646 - Motion blurred quad_light is not visible to camera until second node_update

  • ARNOLD-12842 - Fix possible memory leak when assigning structurally equal array to a node

  • ARNOLD-12845 - Crash report sent even when Arnold is not used

  • ARNOLD-12863 - License incorrectly released when multiple renders are running and some have skip_license_check turned on

  • ARNOLD-12872 - AutoTX regression with inverted view transforms

  • ARNOLD-12876 - Crash with ginstanced points

  • ARNOLD-12891 - Crash when imager is passed to deep driver

  • ARNOLD-12895 - AutoTX keeps original file open after creating TX file

  • ARNOLD-12905 - AiErrorReporting* python bindings are missing

  • ARNOLD-12923 - Arnold crash reporting does not work in non-ascii directories

  • ARNOLD-12928 - Crash if the instancer source node list contains null

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 chip are natively supported.
  • 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 495.46 or higher drivers on Linux and 511.09 (Quadro), 511.09 (GeForce), or higher on Windows. See Arnold GPU for more information.
  • OptiX™ denoiser requires an NVIDIA GPU with CUDA™ Compute Capability 5.0 and above.

The driver type must be set to DCH.

In the driver page, select "Windows Driver Type:" DCH

The cache also needs to be re-populated after installing a new Arnold version, updating to a new NVIDIA driver , or changing the hardware configuration of GPUs on the system. More information can be found here.
