I know how to create front and back ortho views and get a different image in each, but I want them both to face the same way rather than them be mirrors of each other. How is that done in 2.8? I know this is possible in previous versions of Blender because I've seen it a tutorial. I made this video with details here - https://youtu.be/MBJtgHXZMPE
You can use "Local Collections" filters in each viewport to filter out your different backrounds.
Place each of your images in a different collection.
Place your work objects in a third collection.
Create 2 viewports by click-dragging the edge of the 3D viewport.
Expand the "N" panel, then go to the "View" panel, go down to "Collections" and check "Local collections" in both viewports.
Now click the eye icon of the background collections in each viewport.
You can split your viewport, then hover with your mouse over them and press for one viewport Numpad 1 (Front) and for the other one Ctrl + Numpad 1 (Back). Hover with your mouse over the viewport and press Shift + A , select Image and Background.
This image appears only in the selected viewports background and only in the selected orthographic view.
Do this for both viewports with separate images.
