Post-Processing Bloom Bloom effects using UnrealBloomPass for luminance-based glow and selective object bloom. Quick Start Core Concepts How Bloom Works 1. Threshold — Pixels brighter than threshold are extracted 2. Blur — Extracted pixels are blurred in multiple passes 3. Composite — Blurred result is added back to original image Key Parameters | Parameter | Range | Description | |-----------|-------|-------------| | | 0-1 | Brightness cutoff for bloom (lower = more glow) | | | 0-1 | Softness of threshold transition | | | 0-10 | Bloom brightness multiplier | | | 0-1 | Blur spread/size | | |…
