Q: I have already rendered the 1:1 previews and I still get: “Rendering: File Changed…”
A: It means that you have changed the photo in Lightroom since rendering the last time you rendered the 1:1 preview. Either you have done:
- Cropping and not viewing the photo at 1:1 preview
- Made changes using Lightroom’s Quick Develop panel in the Library mode.
- Applied a preset, when not viewing at 1:1
- Any change and not doing it during a 1:1 preview
You can regenerate the standard previews and the 1:1 previews from Library menu
