System Requirements
Houdini, Houdini FX, Houdini Indie, and Houdini Education
19.0.720
19.5.773
20.0.547
Linux with at least glibc 2.28 and libstdc++ 9.3.1 (gcc 9.3.1) for Houdini 19, 19.5, and 20. This is equivalent to RHEL/CentOS 7.
Linux with at least glibc 2.17 and libstdc++ 11.2.1 (gcc 11.2.1) for Houdini 20. This is equivalent to Rocky 8.
macOS 10.13 or later, macOS 11 or later for Houdini 19.5
Apple Mac models with M series chips:
Natively supported by Arnold for Houdini 19.5
Supported under Rosetta 2 mode for older versions of Houdini
x86-64 CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chip are supported natively mode.
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 535.104 or higher drivers on Linux and 537.13, or higher on Windows. See Arnold GPU for more information.
