I’m just curious if there’s a way hide everything but your selection with a single shortcut, rather than selecting everything around what you want to isolate, and then hiding. I’m basically looking for a way to isolate my selection (could be a single actor, could be multiple).
Go to Editor Preferences and bind a key combination to Invert Selection (Ctrl+I would be standard). Then just select what you need, Invert Selection and hide.
Select obj > Right click > Visibility > Show only selected
