How do we add our own crests?

Well the hard part is you actually have to make the crest in Photoshop or Gimp or something. Then place it in the MyGames/FallenEnchantress/Mods/GFX folder. I'm not sure if it will be added to the faction editor but if not then create the faction then go into the Races folder and manually change it in the xml.

In order to make a logo show up you have to make a entry for it as seen in the CoreLogos file.

LAst time I tried this, core logo made these useable, but did Not appear in faction editor. Ill try again tonight. Making crests is pretty easy if you just want new color schemes of existing. 

Kind of wish they would use menus more friendly for say a 100 logos or more lol. 

Sadly, adding logos and to core logos alone will not allow you to use logos in the faction editor. You CAN REPLACE logos, and you can simply rename them so that they are ordered differently.

For example I plan on grouping all of the different animal variants together for ease of use and organization.

PS: Yes I know you can add the logo to the faction through the XML. But for ease of use for non-modders (the people we may be aiming to please) this is a bummer.

It's enough of a pain that I generally wait and look for packs of them, well that is what I did in the first elemental. 

I created several logos here:  https://forums.elementalgame.com/423899  if anyone is interested.   If you look farther down in the thread I've made a few that were used in the Expanded Factions Mod.  Enjoy.
