Save Scene in DAZ Studio

In DAZ Studio, add a character and give her hair and some clothes. Also shape the character to the desired shape.

Save the scene as a DSON User File (*.duf), which is DAZ Studio's internal format.

We will call her Aiko, so we choose the file name aiko.duf. Also rename the character in DAZ Studio. This is important because this name will appear in Blender, and we don't want all our characters to be called Genesis 8 Female.
