Physical Atmosphere - Physics-Based Sky and Atmosphere for Blender

Physical Atmosphere is a professional Blender addon for real-time physics-based sky, lighting, and atmospheric rendering. Trusted by artists across studios worldwide in film, automotive, aerospace, and architectural visualization.

Real-Time Physics-Based Atmospheric Rendering

Physical Atmosphere uses photometric measurements and analytic air mass volume calculations to deliver scientifically accurate atmospheric scattering in real-time, working seamlessly in both Eevee and Cycles render engines.

Key Features

Real-time rendering in Eevee and Cycles. Physics-based sun simulation from temperature, energy output, and limb darkening. Eclipses that actually work. Accurate sunset and sunrise color shifts. Procedural stars with atmospheric scattering. Procedural clouds with dynamic lighting. Full keyframe animation support for all parameters. Lightweight and fast.

Physical Atmosphere vs HDRI

Physical Atmosphere replaces static HDRI sky lighting with a fully dynamic, animatable system. No multi-gigabyte files, no locked-in conditions. Every atmospheric parameter is adjustable in real-time with instant viewport feedback.

Developed by Martins Upitis

Physical Atmosphere is developed by Martins Upitis with over a decade of R&D in physics-based rendering for Blender. Compatible with current Blender versions.
