a simple plugin for Unreal Engine 4 which adds a few basic blueprint nodes
What this is:
...my first attempt at making a plugin for UE4.
...a great way for me to learn and practice my C++ skills.
...a collection of nodes that solve very specialized problems, particularly related to XR development challenges.
What this isn't:
...relevant or useful for most developers, especially those not working in XR.
...anything ground-breaking or new. I think most of this stuff is in Rama's Victory plugin, actually. But I wouldn't learn anything if I didn't make it myself.
This plugin basically just adds a few non-essential Blueprint nodes and exposes some engine stuff for Blueprint devs. The most useful thing in here, for most developers, is probably the ResetOrientationAndPositionZ node. This node drops the Z component of the transform when re-centering the user's XR playspace. It's super useful for maintaining the floor level and only adjusting the center position.
Everything else in here was something I needed for a project at some point or another. By collecting that stuff into a plugin, it makes it really easy to bring changes with me across engine versions.
First, you'll need to grab the plugin from our GitHub repository. Then follow these steps.
Place the 'InnerLoopLLC ' folder in 'Engine/Plugins/Marketplace' or your project's 'Plugins' folder
