REAL BLOOM is a high-performance, physically-inspired bloom and lens effects plugin for Unreal Engine, designed to recreate authentic optical light diffusion, glare, and anamorphic lens artifacts found in cinematic cameras and high-end optics.
It focuses on progressive pyramid filtering with multi-level downsampling and tent upsampling — delivering smooth, artifact-free bloom with film-quality anamorphic streaks: horizontal/vertical light leaks, controllable attenuation, color tinting, and thickness control.
Perfect for cinematic productions, sci-fi environments, cyberpunk aesthetics, racing games, or any project requiring professional-grade bloom—where light should feel luminous, organic, and photographic.
Core REAL BLOOM features:
BLOOM:
Multi-level downsampling/upsampling pipeline (1-6 pyramid levels) — inspired by oldschool and modern AAA bloom techniques
box filter downsample + tent filter upsample for smooth, natural light diffusion
Per-level Gaussian blur with adjustable radius, kernel scale, and directional scaling (X/Y)
Luminance threshold extraction with bright-pass multiplier and HDR support
Fast bloom mode for performance-critical scenarios (low-end PC friendly)
ANAMORPHIC STREAKS:
Horizontal & vertical streak generation with independent enable/disable
Threshold-based bright area extraction for realistic lens flare behavior
Attenuation control — streaks fade naturally with distance
Thickness & length control — from subtle to dramatic cinematic streaks
RGB color tinting — warm, cool, or custom streak colors
Multi-pass blur (1-8 passes) for silky-smooth streak quality
Flexible Control System:
UI Window (Window → Real Bloom) — visual editor with live preview
Console Variables (CVars) — runtime control via console commands
Blueprint-ready parameters — drive bloom dynamically (cutscenes, gameplay states, time-of-day)
Per-project configuration — settings saved in Config/DefaultEngine.ini
Perfomance & Optimization:
Compute shader-based (SM5+) — fully GPU-accelerated, minimal CPU overhead
Configurable pyramid depth — balance quality vs performance
Fast bloom mode — skip blur passes for maximum FPS
RDG (Render Dependency Graph) integration — modern Unreal rendering pipeline
GPU stats tracking — profile each pass individually
In‑Editor Workflow
Install Plugin — Enable Real Bloom in Edit → Plugins
Open Settings Window — Window → Real Bloom
Configure Bloom:
Enable Bloom — toggle on/off
Intensity (0-10) — overall bloom strength
Threshold — minimum luminance to bloom
Pyramid Levels (1-6) — quality vs performance
Kernel G (0-20) — Gaussian blur radius
Add Anamorphic Streaks (optional):
Enable Anamorphic Streaks — toggle lens streaks
Streak Length (0-200) — how far streaks extend
Attenuation (0.1-10) — streak fadeoff rate
Tint Color — RGB streak colorization
Horizontal/Vertical — direction toggles
