System Requirements
- Maya 2022, 2023 or 2024
- 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.
- x86-64 CPUs need to support the SSE4.1 instruction set.
- macOS 10.13 or later, macOS 11 and later for Maya 2024
- Apple Mac models with M series chips:
- Natively supported by Arnold for Maya 2024
- Supported under Rosetta 2 mode for older versions of Maya
- GPU rendering works on Windows and Linux only and requires an NVIDIA GPU of the Ada, 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.
