Stylized Post FX: Retro & Cinematic Effects for URP

Key features:

• 4 full-screen effects: Shaped Vignette, Directional Chromatic Aberration, Retro Posterize, Palette Mapping
• Controlled with standard URP Volume overrides: blend between areas, animate from code
• Single Renderer Feature, one-click setup via Tools -> Stylized Post FX
• Effects that are off add no render passes
• Configurable injection point (before or after URP post-processing)

Give your game a signature look in minutes. Stylized Post FX adds four lightweight full-screen effects to the Universal Render Pipeline. You control all of them with standard Volume overrides, so they blend between areas, animate from code and work with your existing post-processing.
