Texture coordinates, also called UVs, are pairs of numbers stored in the vertices of a mesh. These numbers are often used to stretch a 2D texture onto a 3D mesh, but they can be used for other things like coloring the mesh (see Vertex color), controlling the flow across the surface (see Flow map), etc.

UV Map Grids

This is a texture to use while unwrapping a mesh. Sometimes called a custom uv map template, a uv checker, or a test grid.

Good things to have in a uv map grid:

  • A large checker grid to see large distortions.
  • A fine per-pixel grid to see small distortions.
  • Circles help with solving distortion, as it's easier for the human eye to see when a circle is distorted than a square.
  • Unique colors across the map, to see where the UV is tiling.
  • Letters and/or numbers to see when the UV is reversed.
  • Letters and/or numbers to see where a mesh feature is located in UV space.
