Problems with AB Natural Eyebrows and Eyelashes product
Attempting to use AB Natural Eyebrows and Eyelashes product on EM3D G9 female Prudence, must confess I don't know how to use the card eyebrows or the fiber eyebrows but am having no problem with the eyelashes. How do you apply the card and fiber eyebrows is the basic question as choosing the character then clicking on the materials does nothing.

Eybrows' hierarchical material presets work as expected on my side.
Just apply Card materials (from Card sub-folder) if Eyebrows on G9 are Card Style... apply Fiber materials (from Fiber sub-folder) if Eyebrows on G9 are Fiber Style.
I successfully tried this with a different model CJ Riley G9F with the fiber brows as she had a fiber eyebrow on the scene tab, she however has no card eyebrow listed and so I can't use the card brows on her. Prudence from EM3D has neither a card or a fiber brow listed. What now? Simply double clicking on either card or fiber brow product after selecting Prudence's brows does nothing.
If so, this product will bring you nothing 'cause these presets only work for wearable brows rather than the textured brows on figure's Head map.
