I imported a few backgrounds for the vorpX cinema mode and now would like to give them more descriptive names. is there any way to do that after the import?
You can rename the images during the import but not afterwards currently, sorry. The easiest way to handle this is probably to delete and re-import your backgrounds, then you can change the name during the re-import.
If you don’t mind a little ini-edit, you can alternatively change the FriendlyName value in the .ini files that can be found in [Documents]\vorpX\EnvImages.
