Kicking-Out Time
A Local Fog Volume that vanishes around the player standing inside it in Unreal Engine 5.8; also an NPC who looks seated on nothing outside a kebab shop at four in the morning, a parcel of chips hidden inside her trousers, a barber who walks out of his own shop on a Monday, and a hairdresser's ceiling that renders black while the room below it is lit.

Home Lights
A third-party C++ plugin that would not build in Unreal Engine 5.8 (UHT "Unable to find" on a using alias, TWeakObjectPtr operator bool deleted C2280, GetPolyAreaID C2660, GetAnimationBudgetHandle private C2248); a PIE crash on "Attempting to use a container element which already comes from the container being modified" when closing a looped road spline; a DirectionalLight that switched itself off 41 seconds into PIE because a house-lights system adopted it as a house light; ShowFlag.EyeAdaptation 0 outliving PIE and blowing the editor viewport white; navmesh routes over 61 cm garden walls where AgentMaxStepHeight 55 changed nothing; and NPCs who arrive at the chippy and stand outside against the wall.

Fog in the Sky
A volumetric cloud storm that makes one in the afternoon as dark as night, exponential height fog with FogCutoffDistance 0 painting the whole sunset sky one flat colour, the white edge halos a 30 km fog cutoff leaves round every roofline in rain, an unlit horizon cloud band that glows white at night, and wet footprint decals laid back to front, all in Unreal Engine 5.8.

Two Bright Readings
Street lamps that switch on at dusk while the street stays black because the exposure is still pinned to daytime, a lightning bolt from Blender that imports invisible because FBX flips the UV V channel, a lightning flash light placed 312 m up that turns every roof and road white like snow, and a WidgetComponent petrol pump screen that is almost unreadable because the widget material is lit, all in Unreal Engine 5.8.

Substantially Enclosed
An NPC who stops three metres short of a nightclub toilet because a 1.05 m doorway is too narrow for a navmesh agent radius of 35 cm, a heater whose emissive material pulsed to the music, a light A/B test in Unreal Engine 5.8 where 400, 120 and 0 lumens all looked the same, and a hall and cellar blown out white by a pinned exposure and the editor sitting on Low scalability.

Named for What It Wasn't
A Saturday that ran from a riverbed to a secret society. Landscape grass standing

It Was Never the Frame Rate
A nine-second shot of a man in a lorry cab looked like it was running at fifteen

Eleven in the Morning
The daytime street looked identical to the night street, and it was not a grading problem - the sun was set to ten lux against a real daylight figure near a hundred thousand, and with no outdoor exposure authority the automatic metering re-normalised both to the same mid grey.

In Time With the Music
The nightclub got a music-reactive light rig and one dancer who moves in time with the track, and the reason it works is that tempo is measured offline and baked while only loudness is read at runtime.
