so ive made the rig for a tank and the tracks, i made a curve and then i used clusters on the vertex points then connected it to the wheel joints for each side so just changing the curve on the vertex position. Now the track works fine in maya when i move the wheel a portion of the track follows, but when i export it into a fb file and into unity with the animation it loses the joint connection between the wheel joint and the cluster, any ide why this is does the cluster not get exported with in the FBX? https://i.imgur.com/wDZhPzy.png
