Applies the default 33% african/asian/caucasian, 50% male/female mix. I uploaded a picture of the target as applied in makehuman just for fun, but it's actually meant to be used in maketarget; you load target from file and use it to preview how the targets you're working on will actually look in makehuman. Then when you're ready to save your target, set it back to zero (or check "only save active target"). Edit: changed image from "target as applied in makehuman" to a quick demonstration of how I use it in maketarget (in blender).
