Same here, i just fixed the Inkling eyes, but i dont know how to make the Octoling work, sorry (if u got any idea say to my, plis )

(took me a year to realize this)
I think i know why the octoling eyelids has a missing texture, I took at look under their material files via VTFEdit and found that the VMF files (for the octoling eyelids specifically) had a little misspelling problem. For example, instead of having the "$basetexture" "splatoon/fox/foxdarkeyeocto", It has the "$basetexture" "splatoon/foox/foxdarkeyeocto".
