4.2.4 - Arnold for Cinema4d
30 Jun 2022
C4DtoA 4.2.4 uses Arnold 7.1.2.1 and is a minor feature release bringing improvements to the Arnold Sky, USD export and a number of bug fixes.
- 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.
Installation
- Download the Arnold for Cinema4D plugin
- Follow these installation instructions .
System Requirements
- Cinema 4D
- R21.026 and above
- R23.008 and above
- S24.111 and above
- R25.010 and above
- S26.013 and above
Rosetta2 mode for M1 Macs is no longer supported since Cinema 4D S26. This means Arnold can not run on Apple Mac models with M series chips in Cinema 4D S26 and Cinema 4D 2023 at the moment. M1 support is planned in a future release.
- 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.
- CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chips are supported under Rosetta 2 mode.
- 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/GeForce), or higher on Windows. See Getting Started with Arnold GPU for more information.
- Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above.
The cache will also need 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 .
Enhancements
Color correct settings in Arnold Sky and Arnold Light: A new Color Correct tab is added to the Arnold Sky object, quad, skydome and mesh lights, where the linked texture can be color corrected. (C4DTOA-2746)
No constant sky color in viewport: Flat sky color is not displayed any more in the viewport, only textures. (C4DTOA-2755)
Export animation to a single USD file: Animation (frame sequence) is now exported via the Scene Export dialog to a single USD file, instead of multiple files per frame, if no padding (####) is defined in the file name. (C4DTOA-2747)
Drop insertion in the Arnold Node Material: Since Cinema 4D S26.107 nodes can be inserted by dragging them and dropping them on a wire (existing connection between two nodes). (C4DTOA-2769)
