How do I put a group mesh into a class blueprint

I found some game object is a class blueprint actor, but how did game designer make that?

I structured some meshes in game world, and I group them, how can I put this group into a class blueprint?

thank you~

If you already have actors in a level then select them all, do to the properties window, scroll down to Blueprint and click “Replace with Composited Blueprint”. This will ask you to name and save it to a location.

In the future you can create your own blueprints by going to the Content Browser and click New → Blueprint → Actor

Hello, was this feature removed in 4.10.x? I can’t seem to locate.

edit: Doh, found it under ‘Blueprints’ toolbar icon for anyone else new to BP.

You saved me, JDuaneJ.
Thanks for post it!

Also thanks, JDuaneJ. I never would’ve found it either.
