🟣 True Afterimage System – Advanced Afterimage Post Processing
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:
