Detailed Description

A path-traced camera sensor ("sensor.camera.rt_lens") that renders through a configurable lens model (see Util/CameraModelUtil.h for the model contract) instead of the stock linear pinhole projection.

Unlike ASceneCaptureCamera_WideAngleLens, the lens distortion here is not a 2D post-process warp applied to a rasterized cubemap: the lens model is evaluated per-ray inside the path tracer itself, via genuine per-view FPostProcessSettings fields (see RTLensEngineAdapter.h), so multiple simultaneous rt_lens cameras with different lens models do not interfere with each other. Consequently this sensor captures through a single USceneCaptureComponent2D, exactly like ASceneCaptureCamera, and reuses the same standard RGB readback path instead of the WideAngleLens family's 6-face cubemap + compute-shader resample pipeline.

protected

Pins the capture's auto exposure to the daylight histogram window (EV100 10-12, same as the viewport).

Without this the path-traced view's eye adaptation can meter the raw sun-disk radiance and adapt far past the clamp the world volumes intend, blacking out the image.

		TFunctionRef< void(bool bNonBlocking, const FSensorCaptureContext &Context)>	EnqueueReadback
	)

protected

Runs this tick's capture and this tick's readback in the order the world's synchronization mode requires, then returns.

Every path-traced lens sensor must go through here so colour and AOV cameras stay on the same frame.

EnqueueReadback is invoked at most once, only when clients are listening, with the bNonBlocking flag to hand to the ImageUtil::ReadImageData* overload; the callee just issues its own read of GetCaptureRenderTarget().

Synchronous mode: capture first, then a BLOCKING readback of what was just rendered, delivered by FSensorManager's single per-tick ImageUtil::FlushBatchedReadbacks() GPU sync – the frame the client gets for tick k is tick k's render and cannot be dropped. Asynchronous mode: readback first (of the previous tick's pixels), then capture, never waiting on the render thread – one tick of latency and frames may drop under load, but the server cannot stall.

Context is the capture metadata matching the pixels this readback will pull: this tick's in synchronous mode, the PREVIOUS tick's in async mode.
