UE5 Dinosaur Weather System Tutorial

The weather system is a key component in creating an immersive dinosaur world. This tutorial leverages UE5's built-in weather tools and Niagara particles to build a complete meteorological effect chain. Sunny days feature Volumetric Clouds and God Rays to simulate warm prehistoric sunlight. The rain system employs multiple Niagara emitters for distant rainfall, mid-range rain streaks, close-up droplet splashes, and puddle ripples on the ground. Thunderstorm effects use Light Functions to mimic lightning flashes, paired with Audio Components playing synchronized thunder sounds. Foggy and hazy conditions are achieved by combining Exponential Height Fog and Volumetric Fog, dynamically adjusting based on altitude and time of day. The seasonal system globally controls vegetation color and snow coverage via Material Parameter Collections. All weather states support smooth transitions and Blueprint-driven random switching to ensure consistent gameplay without abrupt changes.
