Bloom

• Bloom Intensity – The brightness of the light fringing or glow.
• Bloom Radius – Determines how far the bloom glow extents in pixels.
• Bloom Threshold – The clipping of the bloom glow to bright pixels. A value of 0 means no clipping. Larger values focus the bloom on the brightest pixels.

Warning
The Bloom radius is defined in pixels and this value is not relative to the resolution. This means that the bloom radius will not scale if the Render Output has a larger resolution than the Real-Time View.
