Plugins

F3D officially supports plugins for certain file formats. If you installed F3D using the binary release, there’s no need to manually load these plugins when opening your file. F3D will load them automatically.

However, if you installed F3D using a package manager, it’s possible that the packager chose to bundle the plugins into different packages or to list plugin dependencies as optional in order to reduce the number of dependencies of the main package.

In order to open a file that requires a plugin, make sure you’ve installed all necessary dependencies. You can then specify the --load-plugins=<path or name> option in the command line to load your plugin.

Alternatively, you can add your plugin directly in the configuration file if it isn’t there already. You can specify one or multiple plugins in a single comma-separated list, like in the example below:

{
    ".*(file_extension)": {
        "load-plugins": "plugin1", "plugin2"
    }
}

Supported plugins

F3D supports the following plugins and their file formats:

• alembic: .abc
• assimp: .fbx, .dae, .off, .dxf, .x, .3mf
• draco: .drc
• exodus: .ex2
• occt: .step/.stp, .iges/.igs
• usd: .usd, .usda, .usdc, .usdz
• vdb: .vdb (experimental)

Note: If you downloaded the binaries from the release page, it’s not necessary to specify manually the plugins above. F3D loads them automatically.

Here is how the plugins are searched (in preceding order):

1. Search the static plugins.
2. Consider the load-plugins option given it is a full path.
3. Search in the paths specified in F3D_PLUGINS_PATH environment variable.
4. Search in a directory relative to the F3D application: ../lib.
5. Rely on OS specific paths (e.g. LD_LIBRARY_PATH on Linux or DYLD_LIBRARY_PATH on macOS).

You can also try plugins maintained by the community. If you have created a plugin and would like it to be listed here, please submit a pull request.
