It is a texture of lemon skin. Oil glands can be found on the surface. Remember to apply the scattering / subsurface map to create realistic peel.
This material can be used together with Lemon Slice Cross Section
(Food 0020) to produce a perfect slice of lemon.
The oil gland colour intensity, green tint intensity, skin texture, wrinkle length etc. can be managed through the Substance SBSAR file.
