I have been working on a city scene for more than a month. Today the computer stopped responding after I made some change to the city. So I had to restart the computer. When I reopen CityEngine, the says there is error and go check the log. I don't know where is the log, but now all the work I have done in the scene is gone!!!!
Please help~~~ I don't want to redo all the work again. It's not just a month, we have half-year of work depending on the map. If I rebuild the map, it will not be exactly the same as the old one, and we will have to redo everything for the new map as well!!
Update1: I found the log, I reopened CityEngine at 2016-08-04 17:19
Update2: The .cej file is significantly smaller than other files. So I guess that data is lost. I have exported it to .obj. Tried to import the .obj, but it doesn't show up in the scene. I also have a blender file. But I'm afraid none of them are editable...
The "internal" log is in Window --> show log.
From my current experience once something's gone in CE (the scene stuff) it's gone for good. I think it's a good idea to do daily backups (File --> export --> archive file) and always close the scene before you exit CE.
