1. A computer-implemented method, comprising: determining a respective distortion metric at each location of a plurality of locations in a two-dimensional representation of a three-dimensional object, the two-dimensional representation based on a view of the three-dimensional object, each respective distortion metric indicating a degree of distortion in a mapping between the respective location in the two-dimensional representation and a corresponding location in a surface texture of the three-dimensional object, and each respective distortion metric comprising a product of at least two different techniques for measuring the degree of distortion; displaying a visual representation of the respective distortion metric at one or more of the plurality of locations in the two-dimensional representation of the three-dimensional object; receiving input to modify one or more pixel values of the three-dimensional object at the view; and preventing modification of the one or more pixel values based on the respective distortion metric exceeding a distortion threshold in the one or more of the plurality of locations corresponding to the one or more pixel values.
