I am interested in how the change of a country's model and skin can be set up depending on the ruling ideology, so that when the ideology changes, the unit's appearance changes automatically. For example, in Komi, the model and skin of the unit vary depending on the ruling ideology in TNO, with 4 options available: left, right, democratic, and burgundians.
After digging into the game files, I did not find out how it was done by the mod developers. I can change models and textures, but this topic still haunts me.
