Optionalopts: AutoExposureFeatureOptionsReadonlynameStable identifier used for lookup, signature hashing, and pass-name keying.
When false, the feature is skipped each frame. Toggling triggers a cached-graph invalidation.
When false the underlying pass writes fixedExposure each frame.
Live exposure-compensation knob in EV stops (+1 = one stop brighter).
When set (and not adaptive), the fixed exposure is derived from these photographic settings via EV100. Mutate at runtime for camera-style sliders.
Normalized-units calibration for the physical-camera exposure (see AutoExposureFeatureOptions.physicalSceneScale). Default 1.
EV100 of the current physical-camera settings (NaN if none set).
Histogram-based auto-exposure. Samples
frame.hdr(read-only) and writes a persistent exposure buffer that downstream features (e.g. CompositeFeature) sample. Exposes the buffer handle onframe.exposureBuffer.Toggling
adaptive = falsekeeps the pass in the graph but locks exposure tofixedExposure. The RenderFeature.enabled flag still skips the whole feature if you actually need to drop it from the pipeline — but then any downstream feature that readsframe.exposureBuffermust be skipped too.exposureCompensation (EV stops) biases the final exposure in both modes; mutate it at runtime for a live EV slider.
