Hello to all,
I’m new to the forum and I have no idea if this is the right section to post this question, if it is not, please move it to the right place.
It’s possible to create a 3D environment, and then to export it and to use it as a screensaver? Thanks for any help or link to guides/tutorials for this.
P.s sorry for my english 
You’d be MUCH better off doing this in some sort of 3d modeling software, even if UE4 could export to that kind of format, UE4 is meant to run on higher-end machines.
Sounds like a waste of energy to let a UE4 game run as a screensaver 
Yes you can. Interactive/Reactive Screensavers are becoming more popular. For a traditional Screensaver, UE4’s Media movie, Matinee/Cascade, and Playback features could easily be used. Its not uncommon for a game’s title screen to transition into a demo mode, which serves as a Screensaver. So using UE4 strictly for real-time 3D Screensaver is reasonable in my opinion.
You can convert an .exe to a screensaver: http://www.wikihow.com/Convert-an-Executable-File-Into-a-Screensaver
If that doesn’t work there are a number of tools AFAIK to convert an .exe to a screensaver.
So create the .exe from Unreal Editor then “convert” it to the screensaver “format”.
You can create and record it to video and make it screensaver for more powersave
I created a simple one to demo some coding stuff in .NET. It’s just floating text that randomly chooses a font and size from available ones. I’ve always wanted to move that into UE and make it fancy.
