And what about x,y gifs resource pack, to have x,y animated sprites throught a resource pack? Is it possible?
It is, but if they try adding some like those models-
pokestadium.com
they would need to recreate the battle system, actually, remove camera rotation.
On the other hand, they made 3D models, but it would take forever to animate
ALL of them because there are more than 500. Maybe Kolben team will do that in the future, but for now they are working on finishing the story, adding new areas, pokemon etc.
Make sure to check out this resource pack!-Tornado9797's "Pokemon Models Pack"
It could be the thing you are looking for and probably the best existing 3D model resource yet.
