This one is tricky and important to get right. Transfer a uv_1 map with Nearest face interpolated from head, then edit it in a way that the eyelashes align to their bases ĥ). There is really no need for something so small to take such huge space.You can map them where ea eyelashes are mapped Ĥ).
Your item does not need that, so it can be made of one ģ).
As I understand, the eyelashes should be fully opaque, right? The glasses you cloned are made of 2 meshgroups to enable transparency for lenses.
