This is a bugfix release. For the full list of features and requirements see the 7.1.1.0 release notes. .

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 .

• 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.

• Optix™ denoiser requires an NVidia GPU with CUDA™ Compute Capability 5.0 and above.

• We recommend using the 511.09 (Quadro), 511.09 (GeForce) , or higher on Windows and 495.46 or higher drivers on Linux . See Getting Started with Arnold GPU for more information.

• The driver type must be set to DCH.

^{I n the driver page select "Windows Driver Type:" DCH}

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 .
