Right so basically I need to put a fireball on my comp and I motion tracked the spine of a book because I want the fireball to appear like it is coming out of the book, so I tracked it, put it to a null object and parented the position of the fireball to the null object. Here's where the problem is, the position of the null object is on the spine of the book and I want the fireball to be floating slightly above the book so all I need to do is change the position to raise the fireball a little higher however, I cant seem to change the position when I parent the fireball to the null object. it turns red when I parent it because I click alt - and then click on the keyframe symbol and then drag the parent icon to the position of the null object. All I want to do is to change the Y position of the fireball after I've parented it and it just wont change for some reason. Any help you can give me would be great. I'm running on AE 2018.
