However, there's an important detail to clarify first: in the traditional sense (like .dll or .exe add-ons that install directly into the software).
This is the only category of plugin officially supported by Lumion (developed by Act-3D).
If you see websites offering "Lumion render plugins" or "Lumion GPU acceleration plugins" from unknown developers,
These are not plugins for Lumion. They are for other 3D software.
A Lumion plugin is a software component that can be added to Lumion to extend its capabilities. Plugins are designed to integrate seamlessly with Lumion, allowing users to access new features and tools directly from within the Lumion interface.
