Creating and Editing Texture Coordinates (UVs) - An Introduction to Computer Graphics for Artists - page 174

Fig. 10.39 The object outlined in orange has backwards UVs, as can be seen by the backwards
type in the texture map. On right , this has been corrected by mirroring the UVs in a UV editor

hundreds of objects have

10.6.5 Overlapping UVs

Overlapping UVs are not always an error. Sometimes artists overlap texture coordinates
intentionally to use the same texture in different parts of a model, or the same part
of a texture in different places. This is a serious problem if it is not planned, because
the overlapped UVs will receive the same pixels (Fig. 10.41 ). This renders an object
