Currently the Compositor can only be enabled at compile time via the <code>-DENABLE_COMPOSITOR=ON</code> CMake flag in FlightGear. SimGear doesn't require any extra parameters. On Linux one can use <code>download_and_compile.sh --compositor</code>. Once you have a binary with the Compositor enabled and you run it, you will be presented with the default rendering pipeline. At the time of writing, this is the low spec rendering pipeline. If you want to try the [[#ALS|ALS pipeline]], start FlightGear with the command line argument: <code>--compositor=Compositor/als</code> | Currently, the Compositor can only be enabled at compile time via the <code>-DENABLE_COMPOSITOR=ON</code> CMake flag in FlightGear. | ||

If you want to enable shadows on all objects in the ALS pipeline use these options as a startup parameters (in QT GUI or in the commandline) <code>--prop:bool:/sim/rendering/als/shadows/enabled=true</code> and <code>--prop:int:/sim/rendering/als/shadows/sun-atlas-size=2048</code>. If you feel like the shadows are too low-quality (specially in the cockpit), increase the shadow resolution to 4096 or 8192 instead of 2048. | If you want to enable shadows on all objects in the ALS pipeline use these options as a startup parameters (in QT GUI or in the commandline) <code>--prop:bool:/sim/rendering/als/shadows/enabled=true</code> and <code>--prop:int:/sim/rendering/als/shadows/sun-atlas-size=2048</code>.
