Pokémon Model Ripping Project

Why do some of the textures seem to not be included with some tree models?

   
Here the only texture listed is plants_me_tree_beech01_trunk01.

Yet when I load the model in Blender, there's also plants_ivy01_01 and plants_beech01_branch01_01
   

I can't find those two textures no matter where I look.

Update: found them in the tr_share_tex and glb_share_tex folders.
