Weather and Time

Time and weather in Project Tourge are part of the drive. The sun moves through the day, weather develops gradually and rain can leave the road wet after the sky begins to clear.

A full day, not a lighting preset

The time system controls the sun's path, the colour of the sky and the balance between daylight and night lighting. Morning light sits differently from midday light, while sunset lowers visibility and changes the atmosphere of familiar roads.

Street lights and building lights respond as daylight fades. The world moves into night as one connected scene instead of swapping to a separate night version of the map.

Weather moves between conditions

Cloud cover, wind, fog and rain transition together. A clear sky can grow heavier, a storm can build and conditions can improve without replacing the whole environment in one instant.

Weather also changes how light reaches the world. Thick cloud can flatten a bright afternoon, while rain at sunset keeps the direction and colour of the remaining sunlight. Time continues underneath the weather rather than being paused by it.

Rain reaches the road

Open areas receive rainfall directly, while roofs and covered sections offer shelter. This affects where the world looks wet and where water continues to build.

The road does not become dry with the final raindrop. Wetness remains and gradually clears, creating a period where the storm has passed but the surface still needs respect. The result can vary along a route depending on exposure and recent weather.

Weather changes available grip

Water affects acceleration, braking and cornering. Tyre compounds react differently as conditions move away from dry asphalt, which gives road-focused tyres and dry-focused performance tyres different strengths.

This does not mean rain simply lowers one global grip value. The driver still feels the car through braking, steering and power delivery, but the available margin changes with the road and tyre condition.

The purpose of the system is variety with consequences. The same road can ask for a different approach at dawn, during a storm or while drying under the evening sky.

The sky changes what the player sees. The road changes what the car can do.
