- Download renderings and current camera properties
- Show statistics about the currently loaded file
- Specify URL parameters to modify behavior on load
- The Physics tab will only be visible if a loaded glTF contains the `KHR_physics_rigid_bodies` extension. It provides functionality to enable/disable/reset the physics simulation, select a physics engine, manually step through the simulation and enable/disable debug visualization.
