Hey,
I use D5 Render pro with the SketchUp Extension.
Today I reopend my D5 project with the “play” button in th SketchUp plugin. But in the D5 project some of my latest changes were gone.
I had the new Auto Safe feature enabled, but I don’t know how to open the “.bak” BackUp file.
Hopefully my changes wich got lost are still saved in the last AutoSave File.
I apologize for the inconvenience. D5 can open only three (3) recent backup files for the time being. You can set the interval of it. In “Menu” → “File” → “View History Version”, you can open the most recent 3 auto-saved projects. As to your case, that is very unfortunate but we can no longer retrieve it. You might need to prepare and set it up right now for future use. Where is the Auto Save feature? How do the backup files work? | User Manual
