Pokémon Model Ripping Project

[Sketchasaurus]

I actually have no suggestion at the moment, as I'm sure more Pokémon-savvy folks will cover that, instead I'm more interested in one thing in particular if you have any insight regarding the following:

Based on some gameplay I've seen, it appears as though the shading on some of the Pokémon changes dynamically while they're moving in battle, I'm curious if there is any data in the textures or materials that is cause for this, or if it's the result of the shader. I'm also interested to know if you know of how the outline is achieved (maybe it's included in the game or 3ds' engine) Ultimately, I'm interested in "reverse-engineering" the render style for parody purposes, so any knowledge regarding the shader and other settings would be a huge help.

Thanks! Keep up the awesome work!
