Has somebody done it successfuly utilizing the mod folder?
The original launch pics is in ..\SteamLibrary\steamapps\common\Galactic Civilizations III\Gfx
There are two files, the smaller one that comes up immediately (with Windows in the back still) and the bigger DDS file when the game goes full screen.
I tried to put other pics with identical file names/format under:
1. ..\My Games\GalCiv3\Mods\Gfx
2. ..\My Games\GalCiv3\Mods\MyGC3Mod\Gfx
None of those methods seems to work, I always get the original pics. I could try to save custom pics by overwriting the original files in the Steam library folders, but (aside from not wanting to mess with original game files) I assume they just get overwritten in a later update again.
It's no biggie, as those launch pics appear really only at launch, but still being able to use custom pics would be a nice touch.
