Using smoothstep(LowerHeight, UpperHeight, currentY) to create an inverse lerp that defines where the fog begins and ends. 3. Core Features of "Advanced" Fog Assets
Standard distance-based fog often creates a "thick air" effect that lacks natural grounding. (Height Fog) solves this by using the world-space Y (or Z) coordinate to modulate density. This allows artists to fill valleys with dense mist while keeping peaks clear, a technique vital for open-world games and cinematic environments. 2. Technical Implementation Advanced fog systems typically use one of two methods: Download File Advanced Vertical Fog Height Fog ...
Allows different colors for the lower and upper fog layers to simulate sunrise/sunset lighting. 4. Performance Considerations (Height Fog) solves this by using the world-space
