Note: For a general primer on installing and using plugins, review Epic’s Unreal Engine 4 plugin system documentation.

Download the SDK Plugin

The latest stable SDK release can be found here.

Import the SDK Plugin

Install the plugin by copying the MixCast folder into Plugins at the root of your UE4 project (you may have to create this directory).

Apply Required Project Settings

Open your project in Unreal. In the Project Settings window, select the Engine > Rendering section and ensure that the Support global clip plane for Planar Reflections option is checked.

Unreal will prompt you restart the editor, which you need to do before proceeding.

Add the MixCast Actor to your Scene

Find the class with the name MixCast SDK Actor in the Modes > Place panel in the All Classes list (the name may vary slightly in the UI depending on Unreal version) and add one of these to each of your available scenes. This handles initializing and managing all MixCast functionality in the SDK.


MixCast has now been integrated into your project. If you’d like, you can now test your integration or customize your project’s MixCast settings!
