Runtime FBX Animation Importer lets you load any FBX animation file from disk directly into Unreal Engine skeletal meshes at runtime — no editor tools, no pre-importing, no cooking required. Whether you're building a character customization system, a modding platform, or a tool that lets players bring their own animations, this plugin handles it all out of the box.

Thread-safe with automatic bone name matching — works with Blender, Maya, 3ds Max, Mixamo, and any major 3D software. Concurrent imports are automatically queued, no crashes, no conflicts.

Works with any Skeletal Mesh — humanoids, creatures, mechanical rigs, vehicles, props, or any custom skeleton.
