@wyattPol Hello. First: Put below lines in your bashrc:

source /opt/ros/humble/setup.bash
export GZ_SIM_RESOURCE_PATH=~/.gz/models

And then run this command again to be sure: source ~/.bashrc Second: Check the structure of models' folder, for example it should be ~/.gz/models/sonoma_raceway and not ~/.gz/models/models/sonoma_raceway

hi! thank you for your help. i have source /opt/ros/humble/setup.bash export GZ_SIM_RESOURCE_PATH=~/.gz/models in my bashrc, also the model's folder structure is correct like you mentioned. but it still doesnt work. i dont know why....

i should close all the old terminals and open new terminal,then it works,it can read models now.
