Hey Guys,  
I hope you’ll are safe and doing well,

I wanted to ask how do I use the different models like `plane`, `iris_depth_downward_camera`, etc present in the location `PX4_Autopilot/Tools/sitl_gazebo/models` in Gazebo simulation?

I realised simply passing the model name as an argument to `vehicle` does not work; it leads to many different errors like saying that it could not find the `jinja.sdf` file for that particular model (and that file in fact really does not exist for many of the models instead of some standard ones like `iris`, `vtol` etc.)

I am trying to use the launch `multi_uav_mavros_sitl.launch` which in turn uses the launch file `single_vehicle_spawn.launch`. Any help, leads and resources would be appreciated, TIA.
