As the title mentioned, I made models with urdf files, find some public sdf models, and use the build editor in gazebo to generate walls. However I couldn't find a way to launch them other than launching the urdf model and manually putting sdf and walls in one by one. I've tried to save the built world and launched them but it showed

Resource not found: The following package was not found in <arg name="world_name" value="$(find ros1_wiki)/world/test.world"/>: ros1_wiki ROS path
[0]=/opt/ros/noetic/share/ros ROS path
[1]=/home/rvl224/brian2lee/gazebo/forklift_test/src ROS path
The traceback for the exception was written to the log file

Down below is my launch file and where I saved the world file. I've launched the urdf models successfully using the same launch file without the " arg name="world_name" " line which made me more confused why it showed package not found in the error.

idk why it doesn't find the world package, but after putting in the whole file route

<arg name="world_name" value="/home/rvl224/brian2lee/gazebo/forklift_test/src/ros1_wiki/world/test.world"/>

it works as I expect
