C4DtoA 4.7.4 uses Arnold 7.3.2.1 and is a minor feature release bringing improvements to the Arnold Scatter object.

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

Enhancements

  • Shape alignment in Arnold Scatter: This new option allows you to align scattered shape instances to the surface based on the shape bounding box. Shapes can be aligned bottom, center or top, or placed on the surface at their pivot point as before when custom alignment is turned off. (C4DTOA-3210)
  • Faster Arnold Scatter viewport: Scatter instances are now displayed more efficiently in the viewport, especially when displaying as wireframe or shaded geometry. (C4DTOA-2250)

Bug Fixes

  • C4DTOA-3209 - Nested instances fail to render

  • C4DTOA-3218 - Cinema 4D 2024 does not exit cleanly on Windows

  • ARNOLD-14365 - Fix AiNodeGetMatrix to return node matrix instead of identity after node initialization in batch renders

  • ARNOLD-14779 - AtProfiledLockable not compiling on Windows in newer MSVC due to Mutex::native_handle_type

  • ARNOLD-14893 - [GPU] 4MB GPU memory leak per frame

  • ARNOLD-15041 - Arnold does not run on Linux distros with glibc 2.39 (RHEL 9.4)

  • ARNOLD-15048 - Fix OIDN dll name clash with DCCs by renaming OIDN libraries

  • ARNOLD-15060 - Arnold should not catch C++ exceptions it did not generate

  • ARNOLD-15087 - uv_projection shader uses corrupt UVs for evaluating its default_color shader

  • ARNOLD-15121 - [GPU] crash when CUDA error has no message

  • ARNOLD-15122 - Crash destroying a light that is part of a light group

  • ARNOLD-15136 - Random hang when parallel initializing scene

  • ARNOLD-15169 - Crash when modifying a child node from procedural_update

  • usd#1923 - Fix instance primvar indices with multiple prototypes

  • usd#1929 - Ensure subdiv_iterations is not set unnecessarily during procedural updates

  • usd#1932 - Fix a crash when the number of elements in a primvar is not equal to the number of points

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 and OptiX denoising work on Windows and Linux only and require an NVIDIA GPU with the Maxwell architecture or later.
  • Intel OIDN GPU support is limited to:
    • Intel Xe dedicated and integrated GPUs
    • NVIDIA GPUs using Turing or newer architectures
