If you are wanting something realistic looking (texture wise) I am not going to stray from the vanilla look and feel. DBH of XGM did that by having the Romans use Ferres style Romans and it just completely ruined the cohesion. However, I can improve on the models to make them more realistic. I'm just not gonna stray from the vanilla uniform colors. I'm glad you like the map, the mod will always be improving!
Vesko, I fixed the bug, thanks for letting me know! Here is the file, it's save game compatible. Just stick it in HRTW/data and overwrite.
