（Need help） Eyelashes on the Star 2.0 model

2237490741

I want to style the character's eyebrows to look like those in a product poster, but I haven't been able to find the corresponding parameters. Her eyelashes have two sharp protrusions, but after I import the model, the eyelashes look very smooth.

Looks like something is missing in Cutout Opacity (if using Iray).
