REX Atmos CORE for Microsoft Flight Simulator 2024
Total atmospheric control for MSFS 2024! Real-time, engine-level atmospheric, weather, light, and color tuning.
Atmos CORE is a next-gen atmospheric engine for MSFS 2024 that injects changes directly into the simulator, not a post-process Filter. Tune live weather depiction, atmospheric scattering, particulate haze, lighting, and global tone in real time, with immediate visual feedback. Modular editors (Weather, Atmosphere, Enviro) and robust preset management let you save, share, and autoload looks across devices. Works with Asobo Live Weather, presets, and ActiveSky FS.
Atmos CORE gives you total control over MSFS 2024’s weather, atmosphere, and environmental lighting, live, in real time. Unlike ReShade/NVIDIA-style Filters, CORE operates inside the simulator, injecting physically-based changes at the engine level so the world responds naturally to conditions. Use Live Weather Depiction & Visual Tuning to Fine- tune how real-time weather is rendered. Sculpt the sky with adjustable Rayleigh parameters, scattering height, and phase functions; add realistic haze, dust, or fog via the Particulate Simulation Engine; and precisely balance color and tone with Enviro’s RGB controls. Save, share, and autoload presets with secure local + cloud storage for easy migration. Compatible with Asobo Live Weather, saved/imported presets, and ActiveSky FS, plus upcoming integration with REX Weather CORE. Designed to be safe and non- destructive: exit or reset to revert the sim to default instantly.
