So the purpose of this wiki page is to give information on where to generally to find 2 dimensional art assets in the folders and what kind of file & format size such 2 dimensional art.

(But some parts of this wiki is still WIP)

Generally all 2d graphical assets can be found in RealmsInExile\LotRRealmsInExileDev\gfx\ and RealmsInExile\LotRRealmsInExileDev\gfx\interface and these 2d graphical assets need to be in the format shown bellow;

Dimensions may have increased for some of these, but the smaller dimensions still work.

So, you want to add your newly Created CoA asset you've done to the mod? Well you need to first make sure it has the correct file size as seen above. Then you need to apply your work to the correct path, generally you either deal with colored emblems or patterns, which either goes into \RealmsInExile\LotRRealmsInExileDev\gfx\coat_of_arms\colored_emblems or \LotRRealmsInExileDev\gfx\coat_of_arms\patterns (Ceck examples bellow).

Then when you have applied your dds art asset you need to write it into the 50_coa_designer_(emblems/patterns) each folder has, generally you need to apply it under ### LotR: Realms in Exile ###, that you'll have to scroll down to. Then follow the same structures the other have. On the example bellow you can see ce_cc_sun_harad_02.dds { colors = 2 category = nature } the colors = number tell you how many colours that the dds picture file use, for example the ce_abrakhan_07.dds picture (see bellow) has 3 color that it uses. the category here sets where it will be shown in, on the CoA customizer ingame, so using the example ce_cc_sun_harad_02.dds { colors = 2 category = nature } it shows us that ce_cc_sun_harad_02.dds category is nature and we can see (on the picture bellow) that it is shown in nature in game.

To create a new Category you need to you just need to create a new category in 50_coa_designer_emblems.txt where you normally would have the normal ones, then you need to localize that using file lotr_coa_designer_l_english.yml found in the folder path \LotRRealmsInExileDev\localization\english. So on the first picture bellow you see the art asset, then on the secound you'll see that i have put ce_easterling_claws.dds category code as title_easterling then on the third picture you'll see that i have localized it as "Easterling". After that it will show up ingame ass seen on the fourth picture!

And this should be it for your new CoA to appear ingame! (But if you wanna know more on how to apply CoA stuff for a dynasty or title you're creating, check this wiki page out Coat of Arms Modding )

So to create a MaA icon is simple first you need to get the image you want to use for that icon. Note: Make sure that the images you choose have the scale of 116 x 116 and that's it is properly converted to dds. Once you have your image setup you go to the folder path \LotRRealmsInExileDev\gfx\interface\icons\regimenttypes and place your icons. Now to get them to show ingame you would have to go to the folder path \LotRRealmsInExileDev\common\men_at_arms_types and select the .txt file that you have you MaA in and then go down to where it says something like this (icon = heavy_infantry) then replace the heavy_infantry with the name of your icon and you should be able to see the icon ingame.

The process is very straightforward : add the .png or .dds file in this folder: RealmsInExile/LotRRealmsInExileDev/gfx/interface/illustrations/event_scenes/

Then link the background to a name in this file: RealmsInExile/LotRRealmsInExileDev/common/event_backgrounds/zz_lotr_event_backgrounds.txt

The ambience and lighting should use the ones from the most similar vanilla background, until something custom can be made
