Editor Session Log#
This log will be generated while running UE4Editor.exe or in a specific project. This file is almost always going to be included when needing a log.
This log will be generated while running a Cooked/Packaged Project (ProjectName.exe or ProjectName.app) Always include this if there is an issue with running the packaged game.
These logs are generated any time you Build/Cook/Package a project. File >Package > Platform, Editor Launch On, UFE sessions.

Any time a compile fails in Visual Studio or Xcode, copy all of the Output and paste into a txt file. Often times we only copy the last few lines that say it failed, which really doesn’t give the information that devs need.
