Some objects disappeared in the modeling tab after render After rendering to see how my model looked so far, most of the objects in my scene disappeared from the modeling tab (using 2.8), they aren't hidden, alt H doesn't bring them back and they are set to be visible in the organizer. They are visible in all tabs except for modeling.
You are in an isolated view inside of the Modeling tab.
Go to View > Local View > Toggle Local View or press Num /.
(Blender 2.7: View > View Global/Local)



You know that you're in isolated mode / local view if it says User Perspective (Local) in the top left corner.
