Ive seen some people on youtube play with the favours cosmetic looks off to take advantage of the battle groups looks. When i load up my game it doesnt have that option. My game is updated and i do not run any mods for the game. Is this a unofficial mod or is there some issue with my game?
Select a ship with a favour. Go to the favour selection part. Click on the favour and a small check box is listed next to the description saying show or hide favour. Click it. This turns off the favour for that ship. On the top right of your screen is an option to change the overall look of your fleet. It's called different things for each faction, apart from the Space Marines as they don't have it.
