Motion Warp Plug-In Load Issues

Table of Contents

Sometimes Unreal Engine forgets the variable type or resets Motion Warping references if the Motion Warping plugin isn’t loaded early enough. I have compiled the steps to fixing this issue.

Step 1: Enable the Motion Warping Plugin #

  1. In Unreal Engine, go to the top menu and click Edit → Plugins.
  2. In the search bar, type Motion Warping.
  3. Make sure the Motion Warping plugin is enabled.
  4. Restart the Unreal project if it asks.

Option 1: Force a Reference in Your Project to Ensure Early Load #

This is the most common workaround.

Step 1: #

In your project, create a dummy Blueprint (can be an empty actor or component) and add a Motion Warping Component to it.

Step 2: #

Place this dummy actor in your level (preferably your startup level) or reference it in your GameMode or GameInstance.

Step 3: #

Compile, save, and restart the engine.
By referencing the Motion Warping Component early, Unreal will make sure the plugin is loaded before it’s needed in your blueprints.

Option 2: Add a Reference to the Motion Warping Component in the GameInstance #

This is a more engine-wide solution.

Step 1: #

Open your GameInstance (create one if you don’t have one).

Step 2: #

In the GameInstance Blueprint, add a variable of type Motion Warping Component (you don’t need to assign anything to it).

Step 3: #

Compile and save.
This forces Unreal to load the Motion Warping plugin very early because GameInstance loads before levels and most gameplay blueprints.

Important: #

If none of these fixes work, you may need to:

  • Check that the plugin is enabled in the Plugin Manager.
  • Make sure that all required plugins are enabled at startup.
  • Try migrating your project content to a new clean project to see if the issue persists. Sometimes corrupted project files can cause persistent load order issues.
