Variable: AmbientOcclusionPostFX

const AmbientOcclusionPostFX: Trait<{ enabled: boolean; intensity: number; radius: number; }>

AmbientOcclusionPostFX — screen-space ambient occlusion config (singleton per scene). When enabled, Scene3D adds a GTAO stage to the post-FX stack — see docs/rendering.md "Ambient Occlusion (GTAO)". Composes with every other stage. Values are live uniforms — changes update in place without rebuilding the node graph.

Always forces the scene pass's 'normal' MRT target (same one NPR already forces) — GTAO's alternative depth-only normal reconstruction is broken under this renderer's multisampled depth buffer (a WGSL codegen gap, not a wiring choice; see stackPlan.ts's requiredMrtTargets). A custom- shader NodeMaterial combined with AO on the (previously MRT-free) plain path must emit both MRT targets or its draw is silently dropped.
