When I copy/paste or duplicate an object it becomes an instance of the original. How can I make the new object unique? I want to be able to modify the new object without the original changing also.
The problem is you are duplicating the Actor/Component but not the underlying Asset. If you wanted to make the duplicate fully unique, one way is to first duplicate or copy-paste the Actor in the level, then find the Asset in the Content Browser, duplicate the Asset, and assign the copied asset to the copied Actor/Component.
In Modeling Mode you can use the Duplicate (‘Dupe’) tool in the Create section to do this in a single step.

Thanks! It’s actually in the transform section, just overlooked it.
