I use editor scripting blueprints for set keys and I can see my changes in sequencer but actors still track old keys in viewport. Resolves the problem when I make any changes using sequencer window or restart sequencer. So how can I resolve this problem using blueprint.
Unfortunately this is a limitation of the current system. The UI does not update if you change the data in blueprint or in python. You need to manually force a refresh by closing the sequencer window. We’re looking to address this in an upcoming release.
