the AI does not seem to be able to keep up with the PC’s growth
The 3D model looks bad at bigger sizes.
Did you happen to grow past the limit? (For example 20/10 bellysize and such)? The limit is for visual only, and you can definitely go past that but neither the 3D view or 2D can really make up the difference.
The pathways between scenes could also use some work.
Can you explain a bit more about what you mean with this?
