Hi, you know in 4.14 version unreal creates map build data files and keep the maps data in it. But after building creates multiple map data with same name. Take a look to the image below. You can see the map name is 1 and unreal created 4 map data files with the name of “1_BuildData”. Lets say i have 50 maps and unreal created multiple map data files for each map. The content browser will become complex. Can i delete all map data files and build again? Thank for advance.
Edit: And guess what i have done. Deleted all MAP DATA files and i tought build the game again can fix that. But when i have deleted files unreal crashed. Restarted again and my all maps has deleted
IIRC you can go to world settings>lightmass settings then enable “Force No Precomputed Lighting”, and then build light again to get rid of any old lightmaps.
I never encounter the kind of problem OP has, but I usually right click the content folder and hit “Fixup Redirector in Folder”, and that solves a lot of my problems.
