Hi all, is possible associate a level to a Null Object  from fotogram 15 to 25 and from fotogram 40 to 50 to another Null Object?

Thank you so much for tips and help

Dynamic parenting can be achieved with expressions by weighting the faux "parenting" with a slider. You can look that up in a simple web search. Anything beyond that will require a more specific explanation of what you are actually trying to do.
