- ARNOLD-12936 - AutoTX cannot create tx file due to access denied error on Windows
- ARNOLD-11223 - Precision issues on the curvature shader with threshold set to 0

System Requirements
- Houdini, Houdini FX, Houdini Indie and Houdini Education
- 18.5.759
- 19.0.720
- 19.5.435
- 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 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 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.
