Plugins
Last updated
Lumit is an OpenFX host. Plugins you have installed for other applications that use OFX are found on start-up and offered beside the built-in effects, and behave in the same way.
Where Lumit looks
Section titled “Where Lumit looks”The standard OpenFX locations, scanned once at start-up:
| Platform | Directory |
|---|---|
| Windows | C:\Program Files\Common Files\OFX\Plugins |
| macOS | /Library/OFX/Plugins |
Anything on the OFX_PLUGIN_PATH environment variable is scanned too.
The scan runs in the background. Install a plugin while Lumit is running and it appears the next time you launch.
A plugin Lumit cannot use is reported. The other plugins in the folder are unaffected.
Where they appear
Section titled “Where they appear”In the Effects & presets panel, under the plugin’s own declared grouping as a heading of its own. A plugin declaring no grouping goes under Plugins.
From there it groups, folds, searches, stars and drags exactly like a built-in effect.
Switch one off
Section titled “Switch one off”Switch this plugin off, on the plugin’s right-click menu in that panel. It stops being offered and stops rendering, and the choice is remembered between sessions.
Switching one off takes effect immediately. Switching one back on may need a restart before it is offered again.
Any effect already in a project using a switched-off plugin is kept as it was saved, and renders as if it were not there.
When something goes wrong
Section titled “When something goes wrong”Each plugin bundle runs in a process of its own, so a plugin that crashes takes down its own process and nothing else. The frame it was in the middle of comes back unchanged, and Lumit carries on.
The effect’s card in Effect Controls says which of four things happened:
| Badge | Means |
|---|---|
| This plugin did not render this frame | It crashed, hung, or refused. |
| This plugin is switched off | You switched it off. |
| This plugin is not installed on this machine | The project uses it and this machine has no plugin for it. |
| This build does not know this effect | The project names something the used version of Lumit has never heard of. |
