Unreal Remote 2 is a free iPhone application developed by Epic Games International S.a.r.l. It allows you to test your mobile Unreal Engine 4 projects directly on your development computer. With this app, you can view and control your Unreal Engine game running on your computer using the touch and motion controls of your iOS device.

One of the main features of Unreal Remote 2 is its compatibility with the "Virtual Camera" plugin (Unreal Engine 4.20 or higher). By using this plugin, you can add Virtual Camera functionality to your Unreal Engine Project.

To use Unreal Remote 2, you need to follow a few simple steps. First, enable the "Remote Session" plugin in Unreal Editor (requires Unreal Engine 4.20 or higher). Next, make sure your development computer and mobile device are connected to the same network. Then, select "Play in New Viewport" in Unreal Editor and enter the IP address of your computer into the app. Finally, press Connect and you will see the image from your editor preview on your iOS device, with all touch input processed by your Unreal project as normal touch input.

Unreal Remote 2 is a valuable tool for developers working with Unreal Engine 4, allowing them to iterate on gameplay and input features quickly and conveniently. It provides a seamless connection between your iOS device and your development computer, making it easier to test and refine your Unreal Engine projects.
