Of course, only for photo mode. Just so it’s not with transferring to studio conditions, but in the same place where the character is located. But the character themselves and everyone around could be moved, given any poses and facial expressions, take photos - and after pausing stops, they would all return to their original positions without interrupting the gameplay.
And the topic is unpopular, as I understand, simply because it duplicates already existing ones. When I created it, the forum didn’t suggest to me that similar ones already existed, and I only saw it after publishing.
Just there concepts from engines are shown, but here I took a real existing game where this was implemented. And quite conveniently - you drag the sliders, and stretch the arms and legs however you want, turn the head, and choose any emotion on the face. And each pose can be saved as a template so you can slightly adjust it later if needed: for example, the direction of arms during hugs, or a facial expression. This is much easier than taking a separate photo for every small change, uploading it and creating a new pose that’s almost indistinguishable from the previous one.
