Sorry for the late response! Been sick for the past few days. Anyways to answer your question, you'll wanna set the eye/mouth materials (Assets > CrumpleBob > Materials > Eyes/Mouths > Quest) to VRChat's Toon Standard shader (VRChat > Mobile > Toon Standard). The quest version always seems to get a little scuffed on export and I honestly have no clue what's going on there, so I apologize for the inconvenience.
