One by one:is the AI art still in here? the thread title says completed but is the game still worked on, as in unfinished? and if yes is all the future art AI generated too? as in art in scenes that came after that switch
The AI art is still in.
The thread says "completed" because the main story was finished years ago and since that we got expansions. The devs are a bit unclear about the current status of this last "finishing touch" "Gold patch", but there was a post mentioning at least one more update to the current version (6.5 next month).
The newer art does not seem to be AI generated. At least i didn't find any in the newly released scenes so far.
This game's development took a lot of years and over a dozen artists have been commissioned for varying amount of pictures. Some of the old ones were very much criticized by the community, since the game's standard increased quite a lot over the years. So AI has been used to upscale and "modernize" some of the -mostly old art in the game. The results range from "that's quite nice to" "OMG get this horror off of my screen".
My opinion:
On most pictures, the AI has only been used to upscale them from 4x3 resolution to 16x9 and if i didn't know it happened i wouldn't be able to tell as someone who doesn't draw. These, plus the more recent scenes where no AI was used are fine, so most of the massive art collection is very nice. However, out of the 100+ scenes in the game in about a dozen ones the AI have gone horribly wrong and it can ruin the experience of those scenes.
But if you don't like AI, don't like the aesthetics or simply oppose it out of principle, there was a guy who uploaded the 5.8 gallery, which is AI-free and it can be used to replace the modified pictures with the original ones if you don't mind the lower resolution.
