Hi all, Thanks to everyone's generous help (LeeS, thecrazyscotsman, Deliverator, etc.) I've been able to figure out creating units from existing assets, adding in icons, and a ton of other stuff. My next project is to create simple buildings. For instance, I'd like to create a new Meeting House, but with a blue roof instead of red. From reading all the asset threads, I know @Firebug created a military building with a different roof color (I think). Can someone get me on the right path? What I've done so far is copy and paste the Meeting House ast file into my project, opened up Asset Editor and...I'm stuck. Do I need an external program to change the color or is it editable in text files? No clue what I'm doing . I can't even find the right DDS files for any buildings to edit.
