I wanna ask if I download them all, extract the relevant files & put into my root directory, each different coloured portrait icons corresponding to different teams (e.g. green for Green; tan for Tan; red for Red; etc.)
Also, can you tell me which are the files which dictate each unit's portraits? Since I want to extract only them & put in the relevant directories.
No. The portraits are not tied to team color and use only one global image for all teams. This means only one color for all teams.
Also, individual units cannot be colored for the same reason. All portraits are within the same image file and getting combinations would either require tailoring a unique image for personal use, which I'm not going to do so don't ask, or modding the units .cfg to use a different image, which would cause online desyncing.
I may not make the best maps, or be the best player, but I put a lot of time, effort, and care into my stuff. That counts for something, right? No.
