Multiple font sizes for a single font

[fkassad]

Should I be using a single font for various font sizes?  I'd export my font in a fairly large size using bmfont generator, then I would scale down the font (by scaling the textmesh) to the desired size.  The other alternative is to export two different fonts for the two sizes I want.  Which is the recommended approach?

2 different fonts all the way if you want quality.
The overhead for the smaller font is generally insignificant compared to the larger one. Eg. if the smaller one were 0.5x the size of the full size font, the overhead will be < 1/3.

You can scale small amounts (usually up to 2x up or down) before it starts looking horrible.
