I've been trying to get the Marine_Roach model by MouseTaylor to work for my campaign but I must be missing a step. The download provides a mod that seems to have a single m3a file in it. How do I apply an m3a to a unit? Do I need to extract the assets from the m3a file? I usually change the model of the unit to the desired m3 file, after importing the textures and m3's and whatnot. Any help would be greatly appreciated.
