I have been trying to do roslaunch qlab_gazebo qlab.launch to startup the gazebo simulator with quadcopter in it. But I am stuck at black screen with a Gazebo message saying Preparing Your World Here are the latest logs printed on terminal

SpawnModel script started

Hi @uidp1499,

for how long did you leave the Gazebo loading the environment? Can you please post the entire log, the latest lines are not helpful (they don't contains any error).

I will check asap on my system and come back to you. The first time you run the code may take a bit longer to find the model it needs.
