Houdini_disable_openfx_default_path Review

Set this variable to 1 if Houdini crashes or slows down during startup due to a buggy or incompatible OpenFX plugin installed in the default system path. It forces Houdini to only load OpenFX plugins from paths explicitly specified in HOUDINI_OPENFX_PLUGIN_PATH , giving you full control and avoiding problematic system-wide plug‑ins.

In Houdini, the environment variable HOUDINI_DISABLE_OPENFX_DEFAULT_PATH is used to prevent Houdini from scanning the system’s default OpenFX plugin directories (e.g., /usr/OFX/Plugins on Linux, C:\Program Files\Common Files\OFX\Plugins on Windows, or /Library/OFX/Plugins on macOS). houdini_disable_openfx_default_path

Add it to your houdini.env file for a permanent solution. Set this variable to 1 if Houdini crashes

export HOUDINI_DISABLE_OPENFX_DEFAULT_PATH=1 /usr/OFX/Plugins on Linux

set HOUDINI_DISABLE_OPENFX_DEFAULT_PATH=1
