>>28310923What exactly do you think an "overworld model" would constitute?
It's not like a sprite where it has to be totally redrawn to suit the "camera distance". Even at the upper end of the tri-count spectrum, most Pokemon battle models aren't so complex that they'd actually need a lower LOD model to work in the overworld, at least not for rendering one single Pokemon behind the player. Maybe in like an MMO context with potentially hundreds of on-screen mon models it could be a point to worry about, but for walking down an Alola street, "making the models" is 100% not the reason.
If anything, it's a matter of scale; getting a convincing (i.e. larger than the player model) Wailord or Gyarados behind the player in a way that doesn't obstruct the camera's view of the player or clip into surrounding world geometry sounds like the hard part to me.
