Unity HairFX is a strands based hair system, this supports for Universal Render Pipeline (URP) and High Definition Render Pipeline (HDRP). This hair system is based on open source AMD-TressFX hair framework.

Requirements

Universal / HD Render Pipeline 12.1.4 +

Features

This package includes a new strand base hair system that integrated from the AMD’s TressFX hair system. This hair system supports both Universal Render Pipeline (URP) and High Definition Render Pipeline (HDRP). Our goal is that this real-time strand hair simulation and rendering system support for cross platform from desktop computer, consoles to mobile devices.

While this hair system has a lot more work remains to be done, we’re sharing what we have at the moment. You’re free to use or modify it to fit your productions and build if needed.

Note

The TressFX Exporter plugin for Maya is in Libray/PackageCache/cn.unity.hairfx.core/Maya_TressFX_Exporter~ folder or download here
