Radon – Hexagonal Bloom Shader

for Realistic Glare

Realistic Light Effects

Add Cinematic Bloom to Your Game

Zenteon+: Radon is an advanced bloom shader for gamers who want more than just a soft glow. It emulates a hexagonal camera aperture to create realistic bloom spikes. Whether you're looking for a subtle glow, taking in-game screenshots, or just looking for a different visual flavor, Radon helps you get a sharp, cinematic bloom effect.

What is Zenteon+: Radon?

Zenteon+: Radon is a high-end bloom shader made for users who want more than just a soft glow. It’s built on a physically-based model that mimics how light behaves inside real cameras. Unlike many games that use simple gaussian blur for bloom effects, Radon simulates a hexagonal aperture—just like the six-bladed diaphragm found in many real cameras.

This creates sharp, directional bloom spikes that bring both realism and artistic impact to your visuals. You get the richness of high-end bloom without the heavy performance cost of a full-screen convolution. A built-in diffusion control lets you control how the spikes soften over distance, while optional effects like chromatic aberration and procedural lens dirt add extra depth and character to the final image.

Radon also includes extra features like:

  • Diffusion settings to soften the bloom as it spreads,

  • Chromatic aberration and color fringing,

  • Procedural lens dirt effects that add character to your scene.

Even with all these features, Radon includes a performance mode allowing it to run on low-end to midrange hardware.

Why Use Zenteon+: Radon?

Most bloom shaders prioritize speed over accuracy. Radon flips that equation by offering a physically grounded bloom effect that remains efficient thanks to a built-in performance mode. While more sophisticated than standard post processing bloom, it’s optimized for smooth performance even on mid-range GPUs.

Whether you're capturing cinematic in-game screenshots or want to add a soft texture to your gameplay, Radon provides a layer of polish that elevates your visuals to the next level.

FAQs

  • Radon uses a hexagon-shaped bloom instead of a blur. It looks more like what you'd see from a real camera lens.

  • Not much. Radon has a built-in performance mode that keeps your frame rate high while still looking great.
