Post-process and display settings resolved from PostProcessConfig (plus the user’s persisted overrides, the quality-preset ceiling, and the launch’s render requests). Every Option here is an init-time gate: None allocates nothing.

Fields

post_process: PostProcessTunables

Composite tunables pushed to the post pass. The backend pairs them with the display-output flags it negotiates below (hdr_display / hdr_pq) to build the uniform the shaders read.

taa_enabled: bool

Whether the temporal anti-aliasing pass runs.

ssao: Option<SsaoSettings>

Screen-space ambient occlusion, or None when off.

ssr: Option<SsrSettings>

Screen-space reflections, or None when off.

ssgi: Option<SsgiSettings>

Screen-space global illumination, or None when off.

rt_reflections: Option<RtReflectionSettings>

Requires an RT-capable GPU; backends fall back to SSR without one.

rt_dynamic: RtDynamicMode

How the ray-tracing acceleration structure tracks moving props. Inert when rt_reflections is None.

rt_skinned_geometry: bool

Whether skinned meshes join the ray-tracing acceleration structure. False leaves the BVH over static + instanced geometry only, so nothing animated appears in a ray-traced reflection.

reflection_blur_scale: u32

Per-axis divisor for the roughness-aware reflection blur target.

auto_exposure: Option<AutoExposureSettings>

Auto-exposure, or None when off.

auto_exposure_bias_ev: f32

Authored exposure_ev carried as a bias on the adapted EV when auto-exposure is on; otherwise baked into post_process.exposure.

hdr_display: bool

HDR display request; each backend gates it on its own EDR / colour- space capability probe and falls back to SDR with a warning.

hdr_pq: bool

PQ-encoded HDR output; honoured by Metal today, accepted elsewhere.

temporal_upscaling: bool

Whether temporal upscaling runs.

upscale_scale: f32

Per-axis input-to-output ratio; ignored when upscaling is off.

upscale_backend: UpscalerBackend

Upscaler selector for DirectX / Vulkan (FSR3 / DLSS / XeSS); Metal always uses MetalFX and ignores it.

occlusion_two_pass: bool

Two-pass Hi-Z occlusion request; gated on the bindless cull path.
