Today I followed a tutorial on creating a tile-able chequered texture sample to be used when testing our UV mapping. This is often known as a UV map template, a UV checker or a test grid.
Main things to include in a UV map grid and their benefits.
- A large checker grid to see large distortions.
- A smaller checker 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.
- Letters and/or numbers to see when the UV is reversed.
Additional things to include to further testing, which I have not included on my design:
- Letters and/or numbers to see where a mesh feature is located in UV space.
- Unique colours across the texture to see where the UV is tiling.
Finally, it is important to off-set your pattern to make your texture tile-able when applying it to your UV wrap.
