Pixel streaming lets you make a live stream in your game, in Unreal Engine. I know that Fortnite does this in their game sometimes. The process of setting it up is very easy. I might make a video and post on how to host it on AWS in the future. You might want to do this if you want something to happen in your game live, so your players can see what is going to change.
Before you get started, you need to make sure that you have the newest version of NodeJS installed onto your computer. You can download and install it here: click here
To get started, launch Unreal Engine. Open your plugin settings, and search for pixel streaming, and enable it. You will need to relaunch Unreal Engine after this. Go to edit, then editor preferences, then play, then paste in the following text in the field called Additional Launch Parameters: -AudioMixer -PixelStreamingIP=localhost -PixelStreamingPort=8888
After this, package your project for windows 64 bit. Go to where your project packaged, select the file called .exe and hold alt and drag it, and let go of them at the same time to make a shortcut. Right-click the shortcut, and select properties. add the following text to the end of what is already in the target for the shortcut: -AudioMixer -PixelStreamingIP=localhost -PixelStreamingPort=8888. There must be a space between the end of what is there, and what you add. Press ok to save. After this, go to where you have Unreal Engine installed, and go to the folder Engine > source > Programs > PixelStreaming > WebServers > SignallingWebServer and open run.bat.
Now, if you go back to the shortcut we made before, run that, you should see a new line on the run.bat window that says Streamer connected. Once this is up, go to Click here on your computer, and you should see your game there. To make it so anyone in your wifi network can see it, open up the command prompt and type ipconfig and press enter. When it comes up with the results, copy the link that says IPv4 address, and with that IP address, anyone that is on your network, including phones, can see your game. They just need to type in that IP address into their browser.
