1. A computer-implemented method for generating one or more maps indicating surface properties of an object, the computer-implemented method comprising:
receiving a first set of images of the object captured using a first set of cameras, wherein the first set of cameras is configured to capture light that is cross-polarized with respect to a polarization of at least one light source;
receiving a second set of images of the object captured using a second set of cameras, wherein the second set of cameras is configured to capture light that is not cross-polarized with respect to the polarization of the at least one light source;
generating, based on initial appearance maps associated with the object, a first set of rendered images that lack highlights and a second set of rendered images that include highlights; and
generating one or more appearance maps associated with the object based on (i) a first comparison of the first set of rendered images with the first set of images and (ii) a second comparison of the second set of rendered images with the second set of images.
