Character Replication&Child etc

Hi there! I’m facing poor knowledge of “replication and child” stuff for character. And I can’t’ find a solution. I would be super grateful if someone could help me.

So in summary, I have my main character (inside this character, I have a clothes swap system based on skeletal slots).
And I created a child of my main character to use it inside sequencer.(The difference between them only in animation mode)
Main have animationBlueprint.
Child i set to Custom since i need it.
When with my main character, I, for example, wear glasses and move to a place where my child BP will be active in sequence.
Child BP doesn’t have glasses.
Maybe I need to tick some options in both bps?
