Using PIE
Dropping Notes
While in PIE you can drop Note Actors at your current location, to help you remember areas to work on back in the editor. You use thedn
console command (for Drop Note), followed by the string you want to assign to the note.
For example:
dn fix lighting hereWill create a Note Actor with your player's current location and rotation, with the text fix lighting here.

Ending PIE
When the user hits Escape in the PIE window (or typesquit
in the PIE console), the PIE window will close.
PIE Vs. Standalone
Garbage collection
When GIsEditor is set, garbage collection uses the old Serialization based method, instead of the new realtime GC method. See the GarbageCollection document for more information on the differences.Async loading, level streaming
PIE does not handle level streaming. It loads all of the sublevels into memory. Texture streaming, however, is performed in PIE.Load flags
The load flags and functions (RF_LoadForClient, NeedsLoadForClient()), that specify to only load components and other objects in the editor, will act differently. Since GIsEditor is true, different components may be around in the PIE world than in a standalone world.Kismet
Kismet has a setting to disable links for PIE only.
