Ensure you have the required "Base Figure" (e.g., Genesis 8 or 8.1 Female) installed, or the character might look distorted. To give you more specific instructions, could you tell me:
Find your "My DAZ 3D Library" folder (usually in Documents ).
Double-click the character icon to load the model into your scene.
Which are you planning to use (DAZ Studio, Blender, etc.)?
