Hello. I am having trouble changing the object material configuration in DriveWorksXpress. I did the course from www.driveworksxpress.com where the instruction was given along with the model and the possibility of changing the configuration of the material works correctly. However, when I tried to repeat the functions in my own model, it did not work and the message "Cannot find the 'oak' configuration" appeared. the only difference I found between the two models is visible in the screenshots
How can I define configurations for modifying materials in the model?
