I'm trying to use PX4 gazebo SITL to make a drone simulation under Ubuntu 18.04. However, once the gazebo GUI was started, the system became extremely slow and took minutes to react. I also tried to use the gzclient on mac and connect it to the server in ubuntu, but the following errors were showed:

[Msg] Waiting for model database update to complete... [Wrn] [] URI not supported by Fuel [model://uuv_hippocampus/meshes/uuv_hippocampus_prop.stl] [Wrn] [] File or path does not exist [""] [model://uuv_hippocampus/meshes/uuv_hippocampus_prop.stl] [Err] [] No mesh specified

Does anyone have any ideas?

Gazebo cannot find the STL files and therefore searches the database, which can take a few minutes.

You can either specify the absolute path in the model file, or set the GAZEBO_MODEL_PATH to find the "models" folder. It's usually:

export GAZEBO_MODEL_PATH ="~/.gazebo/models"

Have a look at this tutorial.
