Creating and Editing Texture Coordinates (UVs) - An Introduction to Computer Graphics for Artists - page 156

Fig. 10.13 The UVs for all the maps have been scaled so that the largest of them fi lls the legal 0-1
texture space
Fig. 10.14 When your object is much smaller in one axis than the other, it can be a good idea to
change the size of your map
Fig. 10.15 By proportionately scaling map sizes to reverse a scale operation in the UV editor, it is
possible to increase resolution without increasing the size of texture maps
