VanguardRedTrooperMod
This mod demonstrates the possibility to overwrite base game content (found in .clb files) by simply adding a copy of a clb from the game into your mod.
The VanguardRedTrooperMod will change the color of the Vanguard Trooper into LiberatorInferno red using the Content Editor only.
This mod contains a copy of Human_Species.clb (found in DocumentsParadox InteractiveAge of Wonders PlanetfallModsArnoutModLibrariesFigure_Skin ). This mod overwrites the existing Human_Species.clb in ContentTitleLibrariesFigure_SkinHuman_Species.clb as the priority of the mod is set higher (Priority 1) in the Package Manager then the base game (Priority 0).
This way you can easily change unit appearance without changing resources (found in .rpk files)
