Class: InstanceDrawComponent

Defined in: src/components/renderer/InstanceDrawComponent.ts:19

Batches child MeshRenderers that share the same geometry and materials into GPU instanced draw calls. On start it groups the renderers by a geometry+material key, uploads their world-matrix indices into a storage buffer, and issues one instanced draw per group.

shadowCacheMode

shadowCacheMode: "auto" | "static" | "dynamic" = 'auto'

Defined in: src/components/renderer/RenderNode.ts:437

Shadow cache classification.

• 'auto' (default): renderer is drawn to the shadow map every frame as part of the single-pass render — matches historical behaviour.
• 'static': renderer is drawn only to the cached static depth layer, rebuilt lazily when the light moves or the scene explicitly marks the static cache dirty. Use for buildings, terrain, prop meshes that don't move.
• 'dynamic': renderer is drawn every frame on top of the copied-in static layer. Use for characters, physics objects, anything that moves.

Only consulted when engine.setting.shadow.enableStaticCache === true; otherwise all renderers behave as 'auto'.

Inherited from

RenderNode.shadowCacheMode

Accessors

visibleLayer

Get Signature

get visibleLayer(): number

Defined in: src/components/ComponentBase.ts:46

Composition-layer membership bitmask. The pass / camera / collector filters via

(component.visibleLayer & pass.layerMask & camera.cullingMask) !== 0

Defaults to VisibleLayer.Default (bit 0) so a fresh subclass is visible to passes whose layerMask is VisibleLayer.All (which includes bit 0). Application code can assign project-specific bits (1..31) to organise the scene into composition layers.

Returns

number

renderPass2()

renderPass2(view, passType, rendererPassState, clusterLightingBuffer, encoder, useBundle?): void

Defined in: src/components/renderer/InstanceDrawComponent.ts:124

Encoder-direct instanced draw for the modern frame-graph pipeline.

drawNodesEncoder (the main ColorPass draw path) calls renderPass2, not the legacy renderPass. The base RenderNode.renderPass2 early-returns on !_geometry, and this component owns no geometry of its own — so without this override the whole group is invisible (its child MeshRenderers were already disabled in start()). Here we issue one instanced draw per geometry+material group using the group's representative node, mirroring the legacy renderItem logic but writing straight to the pass encoder.

Parameters

view

View3D

passType

PassType

rendererPassState

RendererPassState

clusterLightingBuffer

ClusterLightingBuffer

encoder

GPURenderPassEncoder

useBundle?

boolean = false

refreshRenderClassification()

refreshRenderClassification(): void

Defined in: src/components/renderer/RenderNode.ts:270

Recompute renderOrder from current pass states and re-bucket this renderer in EntityCollect (opaque vs transparent map).

Called when a material's alphaMode flips at runtime — the pass.renderOrder changes (3000 ↔ 0), but EntityCollect classifies once at addRenderNode time. Without this nudge the renderer stays in its old list and gets drawn through the wrong pipeline (e.g. WBOIT continues drawing a HASH-toggled material).

Materials hop into this via Reference.getReference(material) to find every renderer holding them; sample code can also call it directly after manual state changes.

Returns

void

Inherited from

RenderNode.refreshRenderClassification
