No scene caused. Gen AI was too early in its development back when BG3 was still having concept art made for it, so doubt it was used for that purpose. I should've used the more specific term here as not all AI is Gen AI, but I assumed it was easy to surmise.
As for their statement that no AI generated content will end up in the actual game - the issue with using Gen AI for concept art is that, unless it is discarded for just not being useful, it will instruct how assets, atmospheres and such are constructed in-game. So, yes, it is indirectly AI influenced. Even ignoring the plagiarism issue surrounding learning models, it's just going to make the general visual direction much blander. AI is not good at having a vision, it "generalizes" into the prettiest thing possible. It's watered down.
Concept art is also one of the biggest sources of commissions outsourced to actual artists. If AI is used for creating concept art, that is a huge amount of job opportunities lost for human artists.
