I created a Guardian of Orion mod and mentioned this collection: https://www.nexusmods.com/galacticcivilizations3/mods/129

Good, though they all lack Citizen portraits.

Wierd, Gnolam is using a stock background image. should be present in the game without DLC. Foreground images were all made in Gimp, for all the civs. that said I am using all the DLC myself, but can't think of a reason if you have crusade for it not to show up. maybe they have a trait from one of the other DLC's? Wealthy and Trader seem like they are pretty standard but I have no idea if one came in an update from a DLC other than crusade.

Only difference I see for Gnolam in files is that the LeaderBG image is missing for them

OK, I was running Aidan's Palette mod, which seemed to be the problem for most of them. I'm now seeing every race EXCEPT Gnolam (though I still get incompatibility alerts for the same races I mentioned). Anything special about Gnolam assets that might cause this?

I subscribed to the whole batch, but a lot of these races aren't showing up for me in the civ selection screen when I start a new game including Gnolam, Trilarian, Cynoid, Evon, Eoladi, Silicoid and Terran Khanate. Gnolam and Grendarl also get "Unknown Shipset Style" errors. Do I need DLC to use these? I'm using Crusade, Snathi Revenge, Mercenaries, and expanded ship parts.

I don't think I ever really played MOO1 either, I have it, but I guess MOO2 kinda defines the series. Havn't played the new one. The pics are from that for alot of the races but I hollistically base the traits and abilities off of MOO2 from what I can glean from the wikis. I still need to balance alot of these for crusade though. I updated them so they wern't broken but I have only gone through and rebalanced about half of them (all the ones with the pics of the traits/personalities screen)

The MOO3 races I started adding when I stumbled on a wiki that had the stats for them.

Hm, good question - I got at least one OP faction through the workshop, so it has to be possible... but I don't know how to, either. :/

And actually, I was referring to MO2 & some MO3-species in my case... nothing wrong with MO1, I'm just not used to it that much. ( although the possibility to build several light ships in one turn was nice )

still adding to this, I thought about making the Antarrans yesterday...but then how would I make them OP? Most of these I made a long time ago and just sat on them. theres aother older collection with all the pics from MOO 1 that is quite awesome. would be cool to pair that with sthe star control colletion for a game someday :)

Uhh, no Antarans?...
Okok, just nitpicking. ;)

I do like some of the older ones, but it's still good to have these at least. :)
