Yes this will break the licensing, unless you make a second set of images and add them to the project as a texturing layer, you can read about layers in the in-app help. It’s critical the images used for geometry remain unchanged, as not only will changing them destroy the license it will also mean you will lose your work on the project as a project with unlicensed images cannot be saved. How can I preserve PPI licenses?
edit: by saved I mean recovered to a usable state (it can be saved it would just be useless)
