4.6.8.1

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.
  • On Linux, we recommend 535.104 or higher drivers.
  • On Windows, we recommend 537.13 or higher drivers.
• OptiX™ denoiser requires an NVIDIA GPU with CUDA™ Compute Capability 5.0 and above.
