UVs<\/strong>\u00a0or\u00a0UV coordinates<\/strong>\u00a0are a way of mapping a 2D texture onto a 3D object. UVs are used to tell the graphics card where to find the texture information for each pixel on the 3D object. For a visual representation, we have provided a gif of a cube laying out flat to show how you transition from a 3D object into a 2D flat image.<\/p>\n<\/div>

Why do we need UV’s?<\/h3>\n

In game development, UV mapping is often done using a 3D modeling software program, such as Maya or Blender. The artist will first create a 3D model of the object they want to texture. Once the model is created, the artist will need to create a UV map for the model. The UV map is a 2D grid that represents the surface of the 3D model. The artist will then need to map the texture to the UV map. This can be done manually or automatically. Once the texture is mapped, the artist can then render the 3D model with the texture applied.<\/p>\n

Here are some of the benefits of using UV mapping in game development:<\/p>\n
