Hello. I'm Trying to do a race with various diffrent car models as opponents, but somehow some cars do not appear in race. For exemple I'm trying to do a race with all dlc gt3 cars but Astons, and 911 gt3 are not selected by AI. Is there a way to solve this?
As long as you have them selected in the Opponents list (session menu) you can always add them manually. Once you've loaded the track and you're in the garage, click on the drop down arrow next to Add AI and select each individual car you want to add.
