Decal
A texture with transparency on a floating polygon, so that it appears to be painted directly on the underlying mesh. When placing decals, care must be taken to avoid Z-Fighting.
Decals are commonly used for bullet marks, graffiti, broken edges, tire tracks, etc.
For hard-edged decals use "alpha test" because this is usually cheaper to render. If the decals must be softer (tire tracks in a racing game) then use alpha blend instead.
See also MultiTexture.
