Thank you, sir! You are correct, i needed to add the new armor name to the following code for it to be recognized:

-- modular armors are not in the demo
armors = data.isdemo and {} or {"basic-modular-armor", "power-armor", "power-armor-mk2"},
idle =
{

and make it like so:

armors = data ...

Hello. I just wanted to know, if say i add a new tier of modular power armor to the game, how do i make it look like the Power Armor MK1 and 2s from base game? Because it seems any custom armor added through modding does not change the player's sprite. It leaves it as when the game starts.
