UT3 - Add Detail to Normal Map

[iSOBigD]

It's a great idea to use small, tiling maps to add detail to other maps.

A few simple ideas for detail maps:

Photoshop - Use a "render > Clouds" filter, make it a normal map and then tile it in the UE and mix it with your rock/ground surface normal map.

For face close-ups, you can use a "noise" filter in Photoshop, tile it in the UE3, mask it so it only gets applied to the skin areas of a face, then mix it with your normal map and/or specular map for very detailed low res skin pores.
