MtoA 5.0.0.2 is a hotfix release that uses Arnold 7.0.0.1
Maya 2019, 2020 or 2022
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 chip 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 470.74 or higher drivers on Linux and 472.12 (Quadro), 472.12 (GeForce) , or higher on Windows. See Arnold GPU for more information.
Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above.
