Informations:

These brightskins are derived from a model which come from OpenArena and have to be considered GPL.
I (Cacatoes) downloaded them from the "Super,CTF" game server. You may find more informations about these on the official OpenArena board : http://openarena.ws/board

Edit (23rd October 2010):

I added another version which we also find on OA servers (Found on GOD|Rockets this time), these versions (zz-proskins2) have more luminosity (like more orange instead of red). I think I prefer these ones.

Edit (29th november 2011):

-> How to use brightskins ?

In order to use the brightskins, you have to select 'Sarge' model in game options. You should then set 'cg_forcemodel 1' so it has effect on every players. Setup > Game Options > Force Player Models > ON ! And you're done.
This will only work on UNPURE servers, which is the case of main ROFL servers right now.
