Here is a pack of (7) 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
-Ballpark at Camden Yarks
-Minute Maid Park
You'll find the biggest changes in AT&T Park (see 2 of the screenshots) where I also updated the ads as well.
My plan is to go through the other stadiums I feel, need the improvements and will release them in another pack when I am done.
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.
