How can I create realistic hair rendering on Three.js


I have a .glb file it looks cool on 3d windows 3d viewer but when I load it on three.js it can’t be realistic . I am using MeshPhysicalMaterial for pbr textures. What should I do for more realistic rendering ?

You need to ensure alphaTest is set on the material, not sure if some hair that appears right is actually a texture or polygons, but the parts underneath sure are. Also seems to look like the normal map is missing as well, but it’s hard to tell what is missing or wrong from a screencap only.
