The invention relates to a rendering method and device, and the method and device are used for the rendering of a skin region in a three-dimensional game display frame. The rendering method comprises the steps: determining a skin region in a to-be-rendered frame; building first illumination information for an unmapped skin region according to the setting of a light source; carrying out the subsurface scattering calculating of the first illumination information, and obtaining second illumination information; and applying the second illumination information to a map of the skin region, so as to achieve the rendering of the skin region.
