Hi, when creating mipmaps in OpenGL with gluBuild2DMipmaps, does OpenGL create mipmaps of the size the texture is and smaller, or does it create all levels of mipmaps - the smaller and the bigger ones?

You supply the base level, and gluBuild2DMipmaps builds all the missing mipmap levels needed to form a complete set of mipmaps. The base level is always the larges image of all levels, so the missing levels are always smaller (halved for each level all the way down to 1x1).
