If you click ‘Cook and upload to Steam’, you can choose between Cook as Mod, Map of Total conversion. You will need Cook as Mod. You must fill in the Maps section a map which contains your mod files. For this map you can use a copy of the GenericMod-map in teh GenericMod folder, with the following settings changed:
Primal Gamedata Override: set it to your Primalgamedata
Gamemode Override: set this to your gamemode (if you have changed it)
