Groups inside Blueprint Editor

Hi, I try to create a BP of a building. So I could change the meshes to windows, walls, doors etc. Something like a generator. I would like all my walls sharing the same mesh. Is it possible to make groups inside the Blueprint editor? And another question s it possible to make a blueprint out of other blueprints?
Thank you :slight_smile:

Hi, Thank you for your reply. I am trying to find out any online tutorial for making Blueprint out of blueprints but I can’t. Do you have any in your mind?
Thank you
