Harrowfield: the playable preview

A stand-in hospital wing and yard, walked in first person with the S7 survivor and rifle, under Ultra Dynamic Sky and its weather. The building is greybox, made only to test the light: the Apocalyptic Hospital replaces it once it is in staging.

Playing it

Double-click Harrowfield Preview on the desktop. It starts the packaged server with no window, then the game in a 1920×1080 window joined to it. Stop Harrowfield Preview closes both. The keys show for a few seconds at the start:

[ ]hold to run the time of day back or forward (two hours a second) Nnext weather: clear, overcast, rain, storm, fog Pthe building's power on or out Ftorch Hshow the keys again

The start is 16:30, clear, power on. Two of the building's tubes are failing and flicker; the store's is dead. Movement, lean and firing are S7's.

Captures

Taken in the editor's Play-in-Editor at 1280×723, Epic scalability, TSR, with the preview's own exposure for each time of day. Every local light uses MegaLights (turned on by this map's post-process volume, not the project), Lumen with hardware ray tracing gives the bounce light, and Virtual Shadow Maps the sun's and moon's shadows.

The first view, with the key list showing — **The first view.** 16:30 in the yard, with the key list up for its first twelve seconds.

The yard at noon, clear — **Noon, clear.** The yard and the hospital wing in full sun.

The same view in rain — **Noon, rain.** The same view a moment after the weather key: the sky closes in and the light goes flat and cold.

The ward in the afternoon, power out — **16:30, power out.** Low sun through the ward's south windows onto the floor and the beds.

The yard at dusk — **Dusk, 18:25.** The blue hour: a sodium lamp, the lit windows and the doorway.

The yard at night, power on — **Night, power on.** The sodium lamp's cone shows in the air; the wing's windows are lit.

The yard at night, power out — **Night, power out.** The same view after the power key: moonlight only, and the exit sign on its battery.

The corridor at night, power on — **Night, power on, the corridor.** Old tubes, one of them failing further down.

The ward by torchlight — **Night, power out, the ward by torchlight.** The torch casts the rifle's shadow; the moon shows in the windows.

What it is aiming at

References: Silent Hill 2 (2024) for the dark interior by torchlight, The Last of Us Part II for daylight through a ruined building, Hunt: Showdown for the time of day and weather on one map, Alan Wake 2 for practical lights in fog.
The bar for this preview: each capture reads at its time of day with nothing clipped to pure black or white across the frame; the torch never pumps the exposure at night; the power key changes every light on the circuit at once.

Not in it yet

Sun shafts in the air indoors: the dust volumes did not show in the first pass; a dust volume made with a volumetric material comes with the hospital's relight.
Frame rates: the preview is for the look. Frame time is measured at S2 on a packaged build with the horde on screen.
DLSS: not downloaded yet, so the preview uses TSR (D-71).
