4.5.1.3

16 March 2023

C4DtoA 4.5.1.3 uses Arnold 7.1.4.4 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-2927 - Node Material preview does not update properly if the viewport is not visible

• C4DTOA-2931 - Crash when converting C4D material with alpha channel to Arnold material

• C4DTOA-2933 - Random IPR crash with cloned mesh lights

• C4DTOA-2936 - Crash when starting IPR with an empty cached Pyro simulation

• C4DTOA-2937 - Incorrect Light Manager layout if mesh lights are in the scene

• C4DTOA-2949 - Preview scene cloning error when editing a slider in a Node Material

• C4DTOA-2951 - Show imager preset folder gives error if the folder does not exist

• ARNOLD-12991 - Errors in OptiX denoiser cause crashes

• ARNOLD-13027 - kick -o does not work if first output is HALF

• ARNOLD-13045 - Crash when imager is passed to deep driver and has output_suffix

• ARNOLD-13056 - GPU ignores uv_transform.mirror_u

• ARNOLD-13090 - Opening a background image in the Arnold Render View > Display tab crashes MtoA IPR

• ARNOLD-13110 - Crash and hangs when flushing quad lights during IPR

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 525.89 or higher drivers on Linux and 528.49, or higher on Windows. See Arnold GPU for more information.
• For GPU rendering, 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.
• OptiX™ denoiser requires an NVIDIA GPU with CUDA™ Compute Capability 5.0 and above.
