# Gazebo Classic Worlds

This topic provides imagery/information about the Gazebo Classic worlds supported by PX4.

The empty.world is spawned by default, though this may be overridden by a model specific world. Developers can also manually specify the world to load: Gazebo Classic > Loading a Specific World.

The source code for supported worlds can be found on GitHub here: PX4/PX4-SITL_gazebo-classic/tree/main/worlds (opens new window).

Some vehicle models rely on the physics / plugins of a specific world. The PX4 toolchain will automatically spawn a world that has the same name as the vehicle model if one exists (instead of the default empty.world):

The model specific worlds are:
