I made a Butterfly moves with this tutorial: https://youtu.be/PgzjlsZAjjw?t=259
I try to track the Butterfly with camera like in here: https://youtu.be/xeu73JHvl9s?t=218
But now camera is going up and down all the time. I tried to move those empties and tried to change track axis, but no help. Is there any way to smooth or block tracking Z-axis?
