True Afterimage System – Advanced Afterimage & Trail Effects

True Afterimage System is a high-quality post-processing effect for Unity URP that generates real temporal afterimages using frame accumulation. Unlike traditional trail effects based on duplicated meshes or sprites, this system produces physically-inspired ghosting directly from the rendered image. Designed for both developers and artists, it supports Unity's Volume System and a fully scriptable manager, giving you complete control over how and where the effect is applied. Compatibility: Unity 6000.4.0, 6000.3.8, 2023.2.22. Supports both Render Graph pipeline and Classic Scriptable Render Feature workflow. Key Features: Generates authentic afterimage trails using frame history accumulation, not spawned objects (True Temporal Afterimage), Only bright areas contribute to the effect, creating natural and perceptual ghosting (Brightness-Based Persistence), Seamlessly blend different setups across your scene with real-time interpolation (Full Unity Volume System Integration), Control everything via code without relying on volumes (Scriptable Afterimage Manager), Extensive Parameter Control including afterimage decay and persistence, brightness threshold and falloff, color tinting, sampling frequency and accumulation timing, Works directly on the rendered image for consistent results across all objects, shaders, and lighting conditions (High-Quality Post-Processing), Easily add the render feature to any URP renderer and use it in any camera setup (Flexible Integration). Included Demo Scenes: Fast-paced gameplay showcasing dynamic afterimage trails (2D Asteroids-Style Game), Demonstrates interaction with emissive materials and lighting (3D Glowing Geometry Scene), Shows afterimage behavior with particle systems and VFX (3D Particle Scene). Also Included: Pre-configured volume profiles, Ready-to-use demo setups, Full source code and components, Documentation embedded in the asset. Perfect For: Stylized games, Action and combat effects, Sci-fi visuals, Speed and motion emphasis, Experimental rendering and tech demos.
