The description refers to the original cake's translucent snow-like appearance, made of pre-cooked glutinous rice flour. Mooncake is traditionally eaten during the Mid-Autumn Festival (Zhongqiujie).
The package includes a set of two separate UV mapped textures, one for the plate and another for the mooncakes. The textures are hand painted and crafted in Photoshop specifically for the model.
