Texture coordinates, also called UVs, are pairs of numbers stored in the vertices of a mesh, often used to stretch a 2D texture onto a 3D mesh.

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.
