Hi,
For my game I need a solution for some hair. How would you guys make something similar to the hair on his helmet?
A fur shader will achieve this nicely. There are a couple available on the Asset Store:
Quickfur is cheaper, but slightly less flexible. It may well do what you need it to, though long fur does begin to produce artefacts, so keep that in mind.
FurFX is more expensive, but gives you a little more content. The fur here is physics-based, which allows it to interact with the environment. I can’t say for certain whether or not this has the same issue as QuickFur with long hairs, though.
As a final note, QuickFur is compatible with mobile devices, and FurFX has a separate package for mobile usage.
I think that you don’t need any fur shader for long hair. Those shader are not adapted for that but more for short fur or hair.
Look at Polycount Tutorials and you’ll find what you want.
If you want to go further you can build a shader with a simple translucency effect with a map and some anisotropic lighting and a bit rim light.
I am almost sure that they didn’t use a special shader for the fur effect but some well placed planes like @AndreiKubyshkin said.
few planes or strip of polygons with texture of hair
