I have a blend tree that works fine when the enemy is set to be moving forward, but when going backward, the legs do not move. The preview for the Animator component shows the character (model and all) moving backward when I slide the “speed” toggle to less than zero, but when the game is running, and the speed is set to less than zero, the legs simply stand still.
The character is being controlled by a navmesh, with the speed and angular speed being passed to mecanim to display the proper animations.
