Create a camera-correct sky background for a 3D scene with a procedural atmosphere or panorama, horizon haze, aligned sunlight, and coherent environment lighting. Use for architectural skies, outdoor 3D backgrounds, golden hour, and day-to-night sky transitions.

When to use

• architectural skies
• outdoor 3D backgrounds
• golden hour
• day-to-night sky transitions
• procedural sky
• panorama mapping
• environment lighting
• sunlight alignment

When not to use

• adding a second renderer for the sky
• using a background photograph alone to light PBR objects
