Here is my final pack of MVP 12 stadiums with recoloring and level correction work done in order to make them more realistic. I found some stadiums to have a bland and washed-out look and decided to improve some of them.
The modified stadiums in this pack include:
-Citizen's Bank Park (full Ivy covered walls)
-Great American Ballpark
Simply copy(overwrite) the stadium files into your /data/stadium folder.
Thanks to KcCityStar for the inspiration to improve these MVP stadiums as we work on the 2K12 stadiums.
