Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

r.setRes wf doesn't set windowless fullscreen [Mac OSX]

Details are in this other AnswerHub question.

Basically, setting the screen resolution using the console command via either the in-game console command (~ key) or via the Blueprint node Execute Console Command to r.setRes 1920x1080wf produces the exact same results as r.setRes 1920x1080f, both of which create a fullscreen window (on a Mac, the screen slides to the left and the game view occupies a new 'desktop') which still has a border even though it's fullscreen.

Mac OSX 10.9.5. Unreal Editor 4.9.

Product Version: UE 4.9

Hi Shrooblord,

To be clear is this the border you are referring to? If not, can you provide your machine's specs and a screenshot showing the borders.

Hi Shrooblord,

We have not heard back from you in a while so I am closing this thread for tracking purposes. If you continue to experience problems with the editor creating a bordered full screen on your MAC, please respond with the requested information and we will continue to investigate the issue.

I do have the same problem. f or wf at the end of the command doesn't change anything, the window border is still there... Unreal Engine 4.9.2, Windows 10

I forgot to mention that I am using the windows version of the UE4.

I am unable to recreate this on Windows. Will you post a screenshot of the border to make sure to ensure that we are addressing the specific problem.

I just created an empty project, created a new Scene and made an animation. When I wanted to play it in fullscreen, it looked like that: alt text

In Windows, that is the screen/window you are going to see when you choose "New Editor Window (P.I.E) This is expected behavior. If you want to view in full screen, simply choose "Selected Viewport (PIE)" then press f11 to enter full screen. Alternatively, you can choose "Standalone Game," and type full screen or "r.setRes 1920x1080f," to enter full screen at that specific resolution.

In the MAC OS, when choosing "New Editor Window (PIE)" it is expected behavior to see the top border and the screen to occupy its own Window. However there is erratic behavior upon returning to the editor after entering the Console Command: "r.SetRes 1920x1080f." This has been reported in JIRA [UE-21914].

If you want to enter fullscreen you can use the same procedures listed for Windows: press f11 while Playing in the editor viewport or in a Standalone Game, type the console command: fullscreen (or "r.SetRes -any resolution- f")
