Hi ,
The functionality of the -DUMPMOVIE command line argument is not broken that I can see. This functionality requires that the project be packaged before this will work.
For instance, I tested this with the Matinee Fight Scene from the Learn tab in the Launcher. Here are my steps:
- I packaged the project and then located the .exe file that allows the game to load.
- I created a shortcut of this > right-click > properties > add -DUMPMOVIE after the .exe
-
In the folder where this is located navigate to the []Projects Name] \ Saved \ Screenshots \ WindowsNoEditor \
-
At this point the screen shots for the rendered frames will be located here.
This will not result in a rendered “movie” like an .avi or .mp4 though. This will give you the rendered frames from your matinee animation that is set to play on start. These images will then need to be used in another application to create your movie, add sound, along with any other that were not handled with matinee (ie. fade in/out).
This documentation here is from UDK, but the process is still the same: UDK | CapturingCinematicsAndGameplay Frames
I hope this helps.
