I'd like to redo the Left & Right paths on a track with a complete AIW defined. Can I simply delete these in Dev Mode, save and exit and let them be regenerated automatically?
No, just drive/save over them. They will update with new data. Load editor. Drive a new path, set as Left. Do same for right. You will need to go back and smooth all the joins to the pits. On each path. Hint, run dev mode in a smaller window. You have easy access to file browser to make backups as ypu go/save. And No, they are NOT auto generated. They always exist. Before they are created, they either follow the cetreline or fast path, I cannot remember.
