I’m not sure, I don’t think the shade smooth in Blender 100% translate into other software’s just as it. From what I understand, each software has its won way of shade smoothing? Something about normal splitting and whatnot. I think it’ll depend on the game engine you’re taking your model into, some of them will get it fine, others have their own way. But again, I’m not sure, it’s just a comment from what I remember JL saying or things on the internet. So for now, when it comes to Blender, I’d say don’t worry about it too much, once you get the hang of modeling and go deeper, those things will come by and then you can take a deep dive in those more advanced topics.
