auto
colorspace by default - usd#1459 - Support shaders with multiple outputs
- usd#1359 - Refresh the Arnold instancer when the prototype mesh points have changed
- usd#1483 - Indexed normals with vertex interpolation are now converted properly
- usd#1462 - Ensure shader scope doesn't appear twice in the hierarchy
- usd#1477 - Fix the motion blur with interframe geometry samples in the render delegate

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.
- x86-64 CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chip are natively supported.
- 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.
