Fast Blur - High Performance Blur Post Processing Effect for URP

Fast Blur is a performant, high-quality fullscreen blur effect built for the Universal Render Pipeline (URP) in Unity 6. Designed as a post-processing override, it integrates seamlessly with Unity’s Volume System and delivers smooth, adjustable blur effects - perfect for UI backgrounds, cutscenes, and in-game VFX.

✨ Key Features

• 🎯 Performance-Conscious Design

Delivers a substantial performance improvement over traditional blur techniques like box or Gaussian blur, while still providing high visual fidelity.

• 🔁 Iterative Blur Algorithm

Combines multiple downsampling and upsampling passes with smart interpolation to deliver high-quality results with fewer samples and lower performance impact.

• 🎚️ Volume-Based Control

Fully compatible with Unity’s volume system. Adjust blur intensity smoothly at runtime using post-processing volumes.

• ⚙️ Renderer Feature Integration

Easy setup as a URP Renderer Feature - just add it to your Renderer Asset and configure your volumes.

• 🛠️ Flexible Applications

Ideal for blurring UI backgrounds, creating atmospheric effects, or enhancing transitions with minimal setup.

⚡ Smarter Blur for Real-Time Projects

While any fullscreen blur effect has a performance cost, Fast Blur is engineered to minimize that impact - offering one of the most efficient blur solutions available for URP. It's a practical choice for developers who want polished visual effects without the steep overhead of conventional blur methods.
