GTA 6 completely "re-engineered" Rockstar's weather systems to "achieve a sense of scale we haven't felt before," adding hurricanes, rainbows and heavy rain

Rockstar Games re-engineered GTA 6's weather system to feature dynamic, localized weather including hurricanes, thunderstorms, rainbows, and persistent effects like wet pavements. The system aims to create a greater sense of scale with fully dynamic cloudscapes rolling across the map, dense atmospherics, and detailed rain effects.
