07 Jun 2021

MtoA 4.2.3 introduces Arnold 6.2.1.1 and is a minor feature release bringing fixes and improvements to OCIO and USD support

Installation

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
Apple Mac models with M series chip are supported under Rosetta 2 mode
CPUs need to support the SSE4.1 instruction set.
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 460.39 or higher drivers on Linux and 461.40 (Quadro), 461.40 (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.
