I have successfully saved several custom camera views.
Using the default keyboard bindings lets me load these views with no issue.
Mapping the load commands to switches on a stick doesn’t work well. When I then go into the controls options and use the “search by input” feature, actuating the buttons on my flight stick correctly presents the “load custom camera” controls.
Only when actuating these ingame, they do nothing.
So
- the custom camera views are saved
- the custom camera views can be loaded by keyboard commands
- load custom camera commands assigned to hardware buttons are recognized by MSFS
- MSFS ignores these
