The main reason is because C3 estimates that the object is off screen. With very large objects, it may not track that well. I added an ACE to scale the bounding box which may help. Try the scale bbox ACE going from 1-2+ times the bbox size. Let me know if it helps.
Thanks for your support, I have one more question. i want these 2 animations to run at the same time but only Plane.003Action works (These are the propellers of airplanes.)
