Struggling to rip sprites from .apk

[lumbud84]

Yep, those gradients are vectors to project the textures in data/textures/cars to the 'psuedo-3D' chassis. It's worth noting that some of the textures are made up of two parts, a main colour layer, and a mask layer. For example, here's 'MyClub.ktx' combined with its mask - it's completely transparent and might be worth noting

The issue is that the only files present in data/textures/cars are the textures they used for cars in the promotional images, which don't appear in the actual gameplay. The way these appear in-game implies that there's a file (or multiple files) that all of these are being pulled from (example image provided), but I can't seem to find where they're being pulled from anywhere in these folders.
I did notice that a ton of the files had an associated mask layer, but I have no idea if there's anything I can actually do with that info.
