[Bug] Gazebo does not show what it should

I downloaded a new version of the program and I can now see the maze in black but not the brown “wood” as shown in the tutorial.
It looks like something is blocking the simulation on your browser, internet connection or PC, because it loads fine, and very fast also (so perhaps it’s not related to connection speed). See the image below.

Things you can try:

  • Use a different browser or Internet connection, if possible.
  • Temporarily disable any Internet Security Suite (some have been found to block the simulation)
  • If possible, check on a different PC.
  • More troubleshooting tips

I can’t progress to the next section even though I’ve selected the green box.
Yes, this is normal, as you are already on the last section of the course.
