Lighting errors on animated models in UDK?

hooblegooblin

I'm using a rigged character from Autodesk's Character Generator as an actor in Unreal Matinee. I converted it to a SkeletalMeshCinematicActor so its animations can be triggered by an event in-game. The problem is, when I build the lighting, there are these patchy blotches of light and shadow across the model.

Does anyone know how to resolve this? An image is attached.
