Xenoblade Chronicles 2 - Modes Rips (Golden Country Stuff Added)

[Demonslayerx8]

Figured I'd ask this XC1DE question here because it seems to apply to XC2 as well and someone might already know: Several models have textures named only "temp0000" that are only red and green channels. What are these for? I'm guessing from context that green is for specularity but have no idea what the red could then be.

Example of Shulk's arm plus bracelet, colour on left and mystery on right:

the 2 channels is for roughness and metal maps, the blue channel is always black, but in XC2, it was for AO maps, but there's no ao maps this time around, altho have came across some for head accessories that uses AO as it's own texture file.
