How can I setup perforce so it diffs using the cool Blueprint Diff tool?

This would be useful so I can diff #4 against #5 (which I don’t think is possible from within the editor).

This doesn’t seem to work for me in 4.17 - I click diff and it just opens the editor to the ‘new project’ page.

Encountering the same issue here in 4.18.1

Now you need to specify project path before -diff.
