Actually RA3 has had support for Brightskins built in for the last few releases ... see an extract of my autoexec.cfg file below:-
-----------------------------------------------------------------------------------
// Set Up ForceModel Change
set cg_forceModel "0"
set fmodelon "set cg_forcemodel 1; set fmchange vstr fmodeloff; echo "^6Force ^6Model ^7On""
set fmodeloff "set cg_forcemodel 0; set fmchange vstr fmodelon; echo "^6Force ^6Model ^7Off""
set fmchange "vstr fmodelon"
bind o "vstr fmchange"
// Set your own model
set model "visor/blue"
set headmodel "visor/blue"
set team_model "visor/blue"
set team_headmodel "visor/blue"
// OSP / CMPA enemy model setting - Note:- Is independant of cg_forcemodel 1.
// RA3 enemy model setting - Note:- Requires cg_forcemodel to be set to 1
// Also Note Server must have the PM files for this to work.
set cg_enemyModel "keel/blue"
// RA3 team model setting - Note:- Requires cg_forcemodel to be set to 1
set cg_teamModel "visor/blue"
// Set sex of yourself for the game engine.
// Note Used in comments like "Player stepped on 'his' own grenade"
set sex "male"
// Force RA3 Skins
set cg_forceSkins "1"
// Color setting for OSP / CMPA enemy model.
set cg_enemyColors "2222"
// Defer loading players to when killed or display scores shown for one second = 1
// Load player models / skins when joining game / new players connect = 0
set cg_deferplayers "0"
// Set RA3 Custom Colours
set cg_customColors "1"
// RGB Color setting for RA3
// FF0000 = Red, 00FF00 = Green, 0000FF = Blue, FFFF33 = Yellow
// FF33FF = Pink, 00FFFF = Cyan, 000000 = Black, FFFFFF = White
set cg_teamColor "FF0000:FF0000:FF0000"
set cg_enemyColor "00FF00:00FF00:00FF00"
set tcolor1 "set cg_teamColor 0000FF:0000FF:0000FF; echo "Team=^4Blue"; set tcolors vstr tcolor2"
set tcolor2 "set cg_teamColor FF0000:FF0000:FF0000; echo "Team=^1Red"; set tcolors vstr tcolor1"
set tcolors "vstr tcolor1"
bind i "vstr tcolors"

If anyone needs a further explaination post back here and I will try and help. I've been playing RA since RA2 was first released. Not that I'm any good at it mind
Oh and I think that comment on the "requires cg_forcemodel to be set to 1" should read "requires cg_forceSkins to be set to 1" and the comment about the server having the PM files may also be redundant these days.
FoRa!
