前言
今天要向大家推薦的是 UnityFurShader，一款【開源】、【專為 Unity 引擎設計】的【毛髮】、【絨毛】、【皮毛】渲染著色器。
這個插件能讓開發者在原生 Shader 中以分層方式繪製毛髮質感，加入【光照計算】與【外力調整】，提升材質的【細節】與【立體感】。
雖然不是完整的物理模擬系統，但在【靜態】或【半動態】場景中已經能呈現相當不錯的視覺效果。
無論你要做【動物角色的皮毛】、【絨毛玩偶的濃密質感】，或是場景中飄動的絨毛植物，UnityFurShader 都是一個【輕量】、【直觀】的選擇。
Unity UnityFurShader 插件介紹
UnityFurShader 是由 Sorumi 開發的開源著色器，核心原理是透過多層 Pass 技術 在模型表面堆疊毛髮層，營造出立體的【毛髮厚度】與【光影效果】。
它結合了基本的光照模型，包括【環境光】、【漫反射】與【鏡面反射】，讓毛髮在不同光源下呈現自然變化。
插件同時提供了屬性控制，例如毛髮【密度】、【細度】與【陰影深度】，開發者能依需求快速調整。
搭配外力 (Force) 模組，毛髮能夠因【全域】或【局部】偏移而展現出簡單的動態效果；最後藉由 Rim Color 邊緣顏色的設計，毛髮在迎光處更具層次感。
需要注意的是，UnityFurShader 僅支援內置渲染管線 (Built-in RP)，對於【URP】與【HDRP】並沒有完整支援。
功能特色
- 分層毛髮渲染 (Layered / Multi-pass)
利用多個 Pass 或多層插值，在模型表面和外沿生成不同深度的毛髮層，創造出毛髮的厚度感與層次感。sorumi.xyz+1 - 光照模型整合 (Ambient / Diffuse / Specular)
在每個 fragment 中計算基本的環境光、漫反射和鏡面反射，使毛髮在光照下有明暗變化。sorumi.xyz - 屬性控制 (Density, Thinness, Shading)
可調整毛髮強度 (density)、毛髮的細度 (thinness)、陰影深淺（根部 vs 尖端）等。sorumi.xyz
適用場景
- 【動物】或【生物】的皮毛
用於表現【狼】、【貓】、【狐】、【熊】等毛皮角色，使其毛髮具【層次感】與【光照細節】。 - 絨毛 / 布偶 / 虹吸材質
適合在模型表面需要呈現【蓬鬆】或【柔軟】質感時使用，例如【玩偶公仔】、【毛毯】、【絨毛抱枕】或【布偶服飾】，帶來細膩的觸感表現。 - 【靜態】或【半靜態】場景物件
在場景中如果有些【毛髮】或【絨毛】物件不需要非常複雜的動態物理互動，只要有輕微偏移變化效果，就能用這個插件。

它包括以下功能：
- 3 種方法（殼/鰭/毛髮多邊形）(Shell / Fin / Fur Polygon)
- 1 使用幾何著色器（和Fin的細分）的通道
- Lit / Unlit 點亮/未點亮
- 使用法線貼圖進行照明計算
- 邊緣光照
- 動畫動作
