The pipeline used on each physical viewport defined on the [[Howto:Configure camera view windows|CameraGroup settings]] can be changed via a <code><compositor/></code> tag containing a valid path to the Compositor XML file (using the [[PropertyList XML File]] format). If no Compositor file is specified for a physical camera, the one given by the <code>--compositor</code> startup command will be used. If such startup option is not used either, FlightGear will look for a valid Compositor file in $FG_ROOT/Compositor/default.xml
The Compositor introduces a new dedicated fgdata directory for new/custom rendering pipelines: $FG_ROOT/Compositor: {{Fgdata file|Compositor}}.
