Sike actually that error also prints out when I run working examples like the built-in sonoma raceway one. And like in that first forum post, the sky doesn't render in that example. The sonoma raceway example isn't even using a sky texture, it just sets the background.

The other error about setting param with empty string can be fixed by downloading the world and editing line 722 of fortress.sdf to <model name="camera_model" element_id="base" action="add"> but it still hangs.

It's just super slow to load so it looks like it hangs. IDK if fixing that was actually necessary.

Ugh this was a pain in the ass. Had to add another camera sensor under the semantic segmentation sensor and it takes 3 minutes each time I want to run it. Anyways, I reproduced the results in that forum post. Even though the sky renders perfectly fine for me in the GUI, in the image preview for the camera it doesn't render, and crashes a few seconds after running the simulation. I think this is because of the hydrodynamics physics. https://github.com/ArduPilot/ardupilot_gazebo/issues/45

First answer is a 404, Second answer doesn't error but doesn't

ACTUALLY, second answer works, I just didn't realize that the launch script I had copied in doesn't read my custom world file, it just puts the robot in a blank world.
