Quick question regarding messed up perspective viewport
 

So I was modeling a helmet, and the next moment my perspective viewport was in the middle of nowhere, I see no grid, models or whatsoever. I tried zooming in and out, I tried selecting an object in another viewport and framing selection in perspective viewport, nothing is working.

My question: How do I fix my perspective view, so I can see my origin and objects again?

try this buildNewSceneUI; type it into the script editor and execute it.

Might help.

Nope :(

Solved by saving the file... then File -> New Scene, and Imported the old save :D:D

So now the viewports are back to standard and still got my objects.
