Constructors

BloomRenderer(RendererContext, PostProcessRenderer)

Initializes a new BloomRenderer using the given renderer context and post-process renderer.

public BloomRenderer(RendererContext rendererContext, PostProcessRenderer postProcessRenderer)

Parameters

rendererContext RendererContext

The renderer context providing shader loading and mesh buffer access.

postProcessRenderer PostProcessRenderer

The owning post-process renderer, used for shared state and format.

Fields

BloomMipCount

Number of mip levels in the bloom accumulation buffer.

public const int BloomMipCount = 4

Field Value

int

Properties

AccumulationResult

Gets the texture containing the final composited bloom result after the upsample passes.

public RenderTexture? AccumulationResult { get; }

Property Value

RenderTexture?

Methods

Load()

Loads bloom shaders and allocates ping-pong and accumulation framebuffers.

public void Load()

Render(RenderTexture, RenderTexture?, BloomSettings, float)

Renders multi-pass bloom from the resolved scene color into BloomRenderer.AccumulationResult.

public void Render(RenderTexture input, RenderTexture? effectsBloom, BloomSettings settings, float sceneWeight)

Parameters

input RenderTexture

The resolved scene color, thresholded before it blooms.

effectsBloom RenderTexture?

Geometry drawn only to glow, bloomed whole without a threshold, or null.

settings BloomSettings

The bloom settings to apply.

sceneWeight float

How much of the thresholded scene blooms: 0 blooms only effectsBloom.
