That\u2019s exactly when the subject of this article – the UV map – takes the stage. Most 3D modeling software creates the UV layout when the mesh is created. However, that doesn\u2019t mean you don\u2019t need to edit and adjust it to fit the requirements of a model. Then there is UV mapping and unwrapping which 3D modeling can\u2019t do without.\u00a0<\/p>\n\n\n\n
