Final result in-engine. (Camera motion is procedurally generated at runtime)
This brief set of animations was created using the default Unreal mannequin and weapon meshes from their built-in First Person Example project. All animation and re-rigging work was completed within Autodesk Maya, the small test scene shown in the video was created within Unreal Engine. Camera motion is generated at runtime using bone location/acceleration data from the mannequin mesh.
