I am unable to get RawTherapee (run from an AppImage) to recognize the contents of any Lensfun database XML files that I add. New lenses do not show up for manual selection in Profiled Lens Correction in RawTherapee but do show up and work in darktable (2.6.2).
OS: Ubuntu 18.04.3 LTS
AppImage: RawTherapee-dev-5.7-152-g7f6d29d-20191025 or RawTherapee-releases-5.7-20190910
I’ve tried adding XML files to ~/.local/share/lensfun and /usr/share/lensfun/version_1. Anything new appears in darktable but not RawTherapee.
What path does Lensfun use to locate database files when it’s used as part of the RawTherapee AppImage? Do new database files have to be added to the AppImage to be recognized?
