Consequences of Piracy

  • Legal Risks: Engaging in piracy can lead to severe legal consequences, including fines and prosecution.

  • Lack of Support: Unauthorized copies do not receive official support or updates, leading to potential issues and vulnerabilities.

How You Can Help

  1. Purchase Legitimately: Always buy add-ons from authorized sellers like SimMarket to ensure you receive authentic products.
  2. Report Piracy: If you encounter pirated add-ons, report them to the authorities or the original creators.
  3. Educate Others: Spread awareness about the negative impacts of piracy and encourage others to support developers by purchasing legitimate copies.

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.

 

Key Features

  • Engine-Level Control: Injects changes directly into MSFS 2024 (not post-process).
  • Real-Time Rendering: Immediate visual feedback while you adjust.
  • Live Weather Depiction & Tuning: Control how live conditions are visualized via Weather Impact Modes.
  • Modular Editors: Weather, Atmosphere, Enviro.
  • Advanced Atmospherics: Rayleigh RGB, scattering height, phase functions, horizon behavior.
  • Particulate Simulation: Haze, pollution, dust, mist, dry heat, fog.
  • Precise Lighting/Color: Global tone + ambient tint with per-channel locks.
  • Preset Management: Save/share, autoload at launch, local + cloud backup.
  • Compatibility: Works with Asobo Live Weather, custom presets, and ActiveSky FS.
  • Future-Ready: Planned dynamics and REX Weather CORE integration.
  • Non-Destructive: Reset or exit to restore default visuals.

What It Is / What It Isn’t

  • Is: A real-time, physically-based system inside MSFS 2024 that changes weather/ atmosphere/lighting at the core level.
  • Isn’t: A surface-level post-processing Filter like ReShade or NVIDIA Freestyle.

Ein sehr schönes Zusatz Produkt was sich sehen lassen kann. Schaut jetzt auf jeden Fall realostischer aus. Aus diesem Grund vergebe ich 5 Sterne!

Only real useful during day time. Not intuitive. Could not see any real advantages.

A small add-on that slightly enhances the atmospheric visuals with subtle tweaks. However, sometimes the presets don’t apply when switching between them. Also, having to reselect preset profiles every time the program is launched gets annoying.

Its a good product behind a bad UX. Its not intuitive and user friendly. Besides that, it does good modifications in the sim.

Great addon, makes the sim much more realistic and easy to set up. I would recommend for IFR rex atmos over Active Sky.

I rarely post comments. Although it is of no benefit to me to post this comment, I decided to post it. This plug-in has completely changed the game. After using it, I can't watch the default game image quality. It's really great and cheap. Believe me, you will thank me.

REX Atmos Core wäre ein viel besseres Produkt, wenn es nicht so eine schlechte Benutzeroberfläche und dynamische Presets hätte. Es ist ein Krampf, eigene Profile zu speichern, diese aktiviert zu sehen und anzupassen. Wenn man jedoch dann mal eine ansehnliche Konfiguration geschaffen hat, kann es sich sehen lassen und es können schöne, "einzigartigere" Atmosphären im Sim erschaffen werden. 2,5/5

Some people in YouTube comments have suggested that reshade or the Nvidia filter could achieve the same effect. This isn't possible. Reshade and the Nvidia filter apply the same filter to the entire image. Atmos Core, on the other hand, only customizes the sky and sunrays, ensuring they hit objects and terrain in a refreshed manner. It's not essential for those who only play MSFS2024 for an hour a day, but it's a crucial tool if you're creating content or want to fine-tune cosmetic effects.

An excellent product! The presets are absolutely beautiful, and the weather injector works flawlessly. It has a minimal impact on performance, which is a big plus. In my opinion, it's better than any other similar product currently available. Highly recommended!

I'll give it 4 stars. It's a simple buy for only 15 Euro. It's like having ReShade but it actually affects the environmental and atmospheric rendering inside the sim. It's pretty basic when it comes down to it. The first 10-15 min are really just struggling to understand what the different settings and levers do. The next 15 are spent tweaking the look of your sim. Some improvements need to be made to the software though: It's hella unintuitive. Give me a tutorial or a manual to explain stuff. If there is a manual, I couldn't find it in the app. Some levers are really sensitive and there is no fine grain control. For example the light settings in the Enviro tab. You basically only use like 2-3% of the range with the rest giving unusable results. A way to have fine grained control like manual entry of values would be appreciated. Third: I want to be able to load all 3 sets with one click. It's a bit of a hassle to go through all 3 tabs and load the sets. There is an autoload feature, but I would also like to be able to load weather, atmos and enviro grouped sets with one click to compare sets. Like I said, it's a nice visual enhancement for the sim, definitely worth the 15 bucks to have some nice eyecandy adjustments.
