INSTALLATION: Choose which version of the ped you have already.
"Vanilla model" is the base game ped, and "Fixed model" is frdfare's updated version of the ped.

There's a backup in case you want to revert back to vanilla.

Place the YMT and YTD files here: "mods/update/x64/dlcpacks/mppatchesng/dlc.rpf/x64/models/cdimages/mppatches.rpf"

After that, save and load in!

You can: Use a trainer to play as her, or go to Director Mode, she's in the "Downtown" category and is named "Student".
 
Or simply find her wandering about in LS, she spawns in these areas: East Vinewood, Downtown Vinewood (at night), West Vinewood (at night), Mirror Park, and can be found at various off-road races in Blaine County.

Not my most groundbreaking mod, but I wanted to make a neat texture mod for my favorite ped in the game, so enjoy!
