Class LightProbeAtlas

Namespace: ValveResourceFormat.Renderer.SceneEnvironment
Assembly: Renderer.dll

Light probe textures shared by all volumes in a scene, each volume sampling its own region. Either the atlas baked into a compiled map, or one packed at load time from volumes that have separate textures.

public sealed class LightProbeAtlas

Inheritance

object ← LightProbeAtlas

Properties

DirectLightIndices

Gets the direct light index texture (lighting version 8.1), or null if no volume has one.

public RenderTexture? DirectLightIndices { get; init; }

Property Value

RenderTexture?

DirectLightScalars

Gets the direct light scalar texture (lighting version 8.1), or null if no volume has one.

public RenderTexture? DirectLightScalars { get; init; }

Property Value

RenderTexture?

DirectLightShadows

Gets the direct light shadow texture (lighting version 8.2), or null if no volume has one.

public RenderTexture? DirectLightShadows { get; init; }

Property Value

RenderTexture?

Irradiance

Gets the irradiance texture.

public required RenderTexture Irradiance { get; init; }

Property Value

RenderTexture

IsPacked

Gets whether the textures were packed at load time.

public bool IsPacked { get; }

Property Value

bool

Methods

Delete()

Deletes the textures if they were packed at load time. Baked textures belong to the material loader.

public void Delete()

FromBaked(SceneLightProbe)

Wraps the atlas baked into a compiled map.

public static LightProbeAtlas? FromBaked(SceneLightProbe volume)

Parameters

volume SceneLightProbe

Any volume that samples the baked atlas.

Returns

LightProbeAtlas?

The atlas, or null when the volume has no irradiance.

Pack(IReadOnlyList<SceneLightProbe>, MaterialLoader, ILogger)

Copies volumes with separate textures into one atlas, and points each volume at its region. Volumes that do not fit or are incompatible are skipped. A direct light texture missing on some volumes is zero there.

public static LightProbeAtlas? Pack(IReadOnlyList<SceneLightProbe> volumes, MaterialLoader materialLoader, ILogger logger)

Parameters

volumes IReadOnlyList<SceneLightProbe>

Volumes with separate textures.

materialLoader MaterialLoader

Material loader the volume textures are evicted from.

logger ILogger

Logger for skipped volumes.

Returns

LightProbeAtlas?

The atlas, or null if nothing was packed.
