Truong CG, who creates many of the best free (and nearly free) rigs for student use, has released the video above to optimise his rigs for Unreal Engine. All of Truong's latest rigs are fully compatible with Unreal Engine since they are all joints-based for both body and face. However, for Truong's older rigs, this video will help optimise the rigs for use in Unreal Engine, giving all the advantages of real-time rendering.
