Texture files are 4k except for the eye texture. All joint pivots have the y axis facing up. The model is to scale at around 6ft tall. The displacement map was exported at mid value 0.5 32bit TIFF. If you don't have Maya you can use the FBX file although constraints and controllers are not translated in FBX. The FBX will still have the joins and skin weights intact. Skin weights still need some finesse.
