Hello there. I am on a mission to figure out why this is not working for me.
What I am attempting to do is have the ability to assign an image to a viewport background as well as remove any image from a specific viewport.

I am having difficulty finding a direct reference to the map assigned to the viewport after it’s assigned.

So far I understand that while i have a specific viewport active, i can query its background image like so:

The problem is that if i want to map a single viewport’s background image using the same syntax, it makes the changes on all 4 viewports.

Which is the same issue if I want to clear a single viewport’s image, and not all 4:

I have attempted other things like:

...and I get the same result.

Any ideas? is there any way to reference a specific viewport’s background image and replace it in any other way than modifying a global variable?

Thanks!

Darned if I can get it to work “as expected” either. Must be possible because the normal dialog (Alt+B) manages it.
May be possible by opening that dialog and using the UIAccessor calls, but it will be messy.
