A unit is the generic measurement used by all 3D software to measure distances and define coordinates.

A unit's relationship to real-world measurements is not set in stone or precise; it is defined only by the scale of a game's content.

  • Units in Id Software and Valve Valve engines are referred to as quake units (qu) or hammer units (hu), and are usually loosely analogous to roughly 1 inch, 0.75 inches, or 2-3 centimeters (see Dimensions).
  • Blender Blender refers to units equaling meters by default, but this can be changed.
  • The Wikipedia icon glTF model standard (supported by Source 2 Source 2's tools and most modern modeling software) mandates units to equal meters, but not all software respects this.
