Hi,

I´ve got a small Los Santos Medical Center to LAC + USC Hospital transformation pack for you.

Installation: 
1. Open OpenIV and enable edit mode.

2. Go to C:\Games\Grand Theft Auto V\mods\x64k.rpf\levels\gta5\_citye\scentral_01
and replace the folder: sc1_08.rpf
optional you can replace also the file: sc1_lod_06_07_08_15_children.ytd
in the path: C:\Games\Grand Theft Auto V\mods\x64k.rpf\levels\gta5\_citye\scentral_01\scentral.rpf\

3. Enjoy it.

It´s highly recommended to backup your file/s before doing any changes.

All the best, Michael : o )
