If I animate, for example, only layer’s position and rotation functions, can I hide other unused functions? By the way, I’ve marked that those unused functions have keys with same values. Can I disable functions that I don’t need at the moment? And are there any filters in timeline, if I want only selected types of function to be shown, pos and screw, for instance?
No, This can only be done in the Xsheet. You can however collapse the element or peg to “hide” all functions. Is there a specific reason you are trying to avoid having keyframes on unused functions?
