7.1.2.1 - Arnold User Guide
30 Jun 2022
This is a bugfix release. For the full list of features and requirements see the 7.1.2.0 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 .
