I use 3Ds Max rendering to texture my high poly models . You should use projection modifier with no cage setup . This pipeline is a usual approach in 3d game development circles . I learned that from Unreal Technology books . . If you go to unreal forums you can find deep explanation how to do it . Also I watched the awesome videos by EAT3D.com . Where the guys lead you through detailed process of normal mapping for Unreal.
