"Derender" right-click option to hide in-world objects
The object and avatar right-click menus would include a "Derender" option, hiding said object or avatar from view. This could either operate similarly to the "Muted" list, or have hidden objects re-appear on re-entry into the region.
This would be especially useful for in-world photography.
This is already present in the viewer as Inhandra Birdsong stated
But this is in the viewer already? Derender is under "Manage" for objects and under "Block" for people.
