Headshot Texture Detail Quirks

You may have noticed that many of the pre-made Sims in The Sims 2 have thumbnails that are less detailed and more polygonal. It is also possible for Sims who are created in-game to have thumbnails like this, though more detailed and less polygonal thumbnails always show the Sim as they look in-game.

If a certain Expansion pack is installed (I think it's The Sims 2: University) this will also happen with the Create a Sim face template icons.

Here are some examples of more polygonal-less detailed and more detailed-less polygonal Sim thumbnails.

Notes:

 * Forgive me for changing the appearances of a few of the Sims, but the pictures on the right are all my fanon content.
