Feature request: Lighting build of multiple maps in squence

you can do this using batch file and ue4editor commandline.
create .bat file (simple txt file with renaming)
write to it

D:\UnrealEngine4\Engines\UE_4.25\Engine\Binaries\Win64\UE4Editor-Cmd.exe “C:\Projects\yourProject.uproject” -run=resavepackages -buildlighting -quality=Preview -allowcommandletrendering -map=F12

D:\UnrealEngine4\Engines\UE_4.25\Engine\Binaries\Win64\UE4Editor-Cmd.exe “C:\Projects\piterGraphics\piterGraphicsC.uproject” -run=resavepackages -buildlighting -quality=Preview -allowcommandletrendering -map=F13

pause

use your engine path, project path, bake quality and map name. you dont need to write full path to your map.
cmd will wait each command to complete.
-run=resavepackages argument is for automatic saving maps after build lighting.
working with 4.25.4 and gpu lightmass. didnt test with other versions.
pause command in the end just leave cmd opened if you want to watch log.

Discussion about baking with commandline you can see there https://answers.unrealengine.com/questions/124936/build-lighting-from-command-line.html
