When I import FBX, the eyelash alphas are not working. I either get them to disappear, or they are all black. Tried tweaking the eyelash node, but I am new and don't know the right thing to input. Any help would be appreciated.
It is related to the material of the eyelashes you imported. Change the material of eyelashes to opacity instead of diffuse and turn down the diffuse multiplayer to 0 at the base tab:
