NOTHING TO READ HERE - It is now all solved with the opt-in from Stardock, as vanilla Retribution disabled mods support!!
And now on with this superb mod!!
I can't make your mod works, sorry. It must be a senior moment from me probably, as I consider that being in the software industry, I should know where to put files.
First question though, is that normal that your archive don't include a StyleShipSet to place in the GC3 mygames directory (C:\Users\<username>\Documents\My Games)?
Now step by step.
Yes, I have mods enabled. I launched thrice the game and each time I see the check box on.
I have placed the 'Designs' directory that should go into the Steam GC3 folder at the proper place, I have been asked to overwrite 82 files if I remember well, I then checked that the new preview images are there alongside the vanilla ones. They are there, no doubt. Anyway the error is not about that.
In the GC3 crusade my game directory, I did place the 3 requested folders. One is the mod, and contains all the mods parts, and it goes in the mods folder, I have removed everything else except the example mod from Stardock. Ah, yes I have all DLCs, including Retribution. Also I did download the Retribution mod you just made, and not the update meant for GC3 without the latest DLC.
The 2 others are your Factions folder and your Designs folder, and they are put where they should be.
So now, launching the game, I get an error on each of your civilization, saying the StyleShipSet is not found. Then I reach the main menu. Clicking on new game, I often get 1-2 of your civilizations displayed, like Minzari commune. If I try to edit it, I see none of your special ability (like Nomad, from the readme) and I see no custom shipset of your (so it explains nicely why the game complains )
I totally fail to see what I did wrong. I have deleted everything now and I'm reinstalling the game from Steam. I have also unregistered to all mods. I don't think it will change anything, but hey, one can hope.
Now, I'm very curious to read from you, I must have missed something gloriously obvious, but what... ?
I have renamed the Factions folder to _Factions, adding an empty Factions folder instead. Game loads fine. There is no custom trait or ability to pick if I design a new faction. Trying a test game, everything seems vanilla, tech-tree wise. BUT
If I design a faction and customize the shipset (you know, replacing Terran cargo by another model, e.g) I do see your work. (DALEK is part of your mod, right?)
For the rest, zip, nada, nothing. It is as if the latest version of GC is not loading, mods, period.
