Tutorial: Using a URDF in Gazebo: Gazebo showing black world
Hi everyone,
I'm trying to make my way through the gazebo-ros tutorials, but now im stuck and need your help:
When trying to spawn the rrbot from the tutorial with command
roslaunch rrbot_gazebo rrbot_world.launch verbose:=true
gazebo starts without warnings/errors and the rrbot is observable in the "World"-Tab on the left side of the gui under "models". Unfortunately the whole world in gazebo is black and therefore I cant see the robot itself.
Am I missing anything? What else could I try to obtain hidden warning?
Hint: I am able to load the rrbot into rViz and there I can also rotate the joints with the joint_state_publisher.
My setup:
- Ubuntu 20.04 LTS on virtual machine
- Gazebo 11.8.1
- ROS noetic 1.15.13
Followed Tutorial:

Thanks for you help in advance :)

This may not actually be the cause, but you mention you're using a VM. Those have traditionally not been too reliable when it comes to 3D accelerated GUI applications. It can work, but it also sometimes doesn't. Artefacts while rendering are one of the problems that can occur.
When i run the empty_world.launch with roslaunch cmd, the world appears normal and i can insert models with no Problem.
