UPD: Added spring helper.
Little script which automatically creates/removes LookAt constraints. Could be useful for testing animations without constant exporting and testing in-game.
But keep in mind, it’s not quite the same as movement in-game. AC moves wheels and SUSP_… according to values from suspension.ini.
You can get it here (press “Raw” button).
And, just for in case, if you want to see an example of DIR_ animation — I’ve shared all source files for Morgan 3 Wheeler.
