Exporting Animation from 3D Packages to Unreal Engine: A Comprehensive Guide

In this blog post, we will delve into the intricacies of exporting animation from your 3D package directly into Unreal Engine. Whether you are working with keyframe animation or motion capture (mocap) data, this tutorial aims to provide you with a clear workflow to seamlessly transfer your animations into Unreal Engine for a smooth integration process.

Keyframe Animation Export Process

Exporting Skeletal Mesh

When working with keyframe animation, the first step involves extracting the skeletal mesh from your 3D software. Here's a summarized workflow:

  1. Name Convention: Ensure unique naming for all components to avoid conflicts.
  2. Reference Handling: Check and resolve any referencing issues, especially if using external references in your scene.
  3. Namespace Check: Remove namespacing to prevent hierarchy issues during export.

Animation Export

The next step is to export the animation itself. Follow these guidelines:

  1. Select Animation: Collapse unnecessary elements in your scene, such as control curves.
  2. Bake Animation: Bake the animation on the skeleton to set keyframes for each bone throughout the sequence.
  3. Time Frame Control: Verify your timeline spans the entire animation duration to avoid frame cutting.

Importing Assets into Unreal Engine

After exporting your skeletal mesh and animation files from Maya, proceed to import them into Unreal Engine with these steps:

  1. Skeletal Mesh Import: Ensure to import the skeletal mesh first, verifying settings such as normals and smoothing groups for optimal results.
  2. Animation Import: Import the animation separately, making sure to synchronize it correctly with the skeletal rig for seamless playback.
