LivePP2

A simple Unreal Engine integration plugin for Molecular Matters Live++ 2.

This is much faster to iterate with than the default Live++ integration, but it comes with an additional restriction: Neither UBT nor UHT will run. If you make any changes to headers that change the line numbers UHT macros are on, it will fail to compile the patch. Basic rule: Just don't use hot reload for header changes.

Supported Platforms

The plugin will work in the editor aswell as packaged builds in Debug, DebugGame and Development config. I only implemented support for Windows.

Supported Live++ Versions

You must use Live++ version >= 2.5.2 for unity splitting compatibility.

Installation

  1. Install this plugin to your project.
  2. Download the official Live++ release and place the LivePP folder next to the PLACE_LIVEPP_FOLDER_HERE file in Source/ThirdParty/LivePPSDK.
  3. Disable Live Coding in Unreal Editor from Editor Preferences -> Live Coding.
  4. Add -LivePP2 to the launch arguments in your IDE.

Usage (Editor)

  1. Start the editor.
  2. Modify a file and use Ctrl-Alt-F11 shortcut as usual.

Usage (Packaged)

  1. Start the packaged build with -LivePP2 argument.
  2. Modify a file and use Ctrl-Alt-F11 shortcut as usual.
