 Backlace 🎀 is a versatile anime (also called "toon", "cel shaded", or "npr") shader for Unity and VRChat. Backlace is packed with a wide range of features- from anime character shading, to screen-space rim lighting, to procedural glitter. Get started with a single click for a typical fully-lit anime character or dive deep into the advanced settings like Pathing and Refraction! (─‿‿─)♡
