Hey Brad,
By 360 Screenshot plugin, you mean the Nvidia Ansel Photography Plugin, correct? There are some settings in the Ansel Console Variable Reference, but I’m not sure if the Auto PostProcess setting might be affecting things or not. This code was taken from the following two pull requests (need to login with a GitHub account linked to your Epic Games account, or the links will just show 404 errors):
Ansel/Photography system #2817
Ansel plugin fixes for master #2855
Since Nvidia makes both the Ansel tool and the Plugin, they’d probably be the best people to ask, but all of the code for the plugin is in the Engine\Plugins\Runtime\Nvidia\Ansel\Source\Ansel directory, so if you’d like to extend it or modify what it does, feel free to change the code. Let me know if you can’t find a way to make it work with the View Modes you’re looking for, and I can reassign this question to nvidia support to see if they have any advice for you. Or, if you look closely on those pull requests the author from Nvidia’s email address is listed, so you might try emailing him directly and see if you have any luck that way.
Thanks!
