Utility widget: Fire event if an actor's properties have changed?

Long story short, in my game each mesh is copied several times at a known offset (basically making a grid of the same small level several times). Designing these levels has been a challenge because if I modify one asset, I need to manually update all the others. I’m looking to automate that.

One idea was to have a utility widget that’s watching the “reference” mesh and then automatically updating all the other “proxy” meshes to match. Is that even possible? Any other ideas on how to approach the problem?

Sure thing!

Use a Construction Script to see the changes immediately without clicking Play

And once one is done - you can duplicate it to your hard coded “known locations”
But you could use some simple math for that matter
