How do I split viewport and place a different empty image in each one? As of now, when I place the empty in one view it appears in the other.
first step is to to place each of your ref images into different collections and your objects into a seperate collection
Now press 'N' on your keypad and go to the 'View panel'
go to the collection section and check the 'local collections' option
Now just repeat the same steps in the other section of your splitted viewport
