I have several blueprints that I always use stored in folders on my pc as text files, to copy and play in an Unreal object, is there any way to create a tab here with these blueprint objects?
You could create a plugin and add it on a per project basis or add it to the engine and enable it per project, alternatively, you could use Editor Utility Widgets.
Easy Asset Creator creates such Categories in the PlaceActor Tab and the Content Browser Context.
What else you can do is create Collections.
You create a collection by opening the Content Browser and on the bottom of your Content Field, you find th Collections Field. there you add a new List and via Drag and Drop push assets into one.
when selecting a collection, only your Dropped assets are listed.
I use both, the plugin and collections… since the Plugin gives me good Features for Asset Factories and Organizing them into new Tabs of the common Content Browsers… while Collections hold all my Item Actors, Enemies, Plants…etc in their own Lists.
