Hi Plishe, we have two similar reports on file (click here
to read the thread).
The only way we've been able to replicate it is by opening a scene saved in 5.7.x in Lumion 5.3.
Have you got both 5.3 and 5.7.x on your PC by any chance? If so, is it possible that you accidentally opened the scene in 5.3? I'm not asking so we can point fingers or anything - I'm just looking for a pattern, so we can start to rule out possible causes.
Unfortunately, there's no automatic way to restore the lost photos, so you'll need to load a previous version of the scene and take screenshots of the camera angles. The next step is to reconstruct each photo in the latest version of the scene based on your screenshots. Sorry about the inconvenience, but fortunately, the effects are still intact, so it could be worse.
I don't know if you're using more than 5 layers in Build
mode, but if so, please note that one of the other users reported that layers higher than 5 had gone missing when it occurred. However, this was easily fixed at he could simply click on the + button to add the layers again - all object assignments on the layers were still ok.
