December 26, 2025Dec 26 From REX: "We are excited to announce that REX Atmos Core – Technical Update 1.0 will be released on Monday, December 29th in the afternoon. In the meantime, the Beta version will remain fully operational. Once the update is available, we strongly recommend upgrading to ensure optimal performance and compatibility."
December 26, 2025Dec 26 Finally, got a taste of Atmos before SU4 came out and have pondered whether I should install the beta in the meantime. Glad to see it's coming out soon!
December 26, 2025Dec 26 Commercial Member Atmos CORE Tech Update 1.0 Changelog: FIXED – Full compatibility with Microsoft Flight Simulator 2024 SU4. Resolved multiple integration points affected by SU4, including environmental data offsets, and API handshake behavior to ensure stable communication. FIXED – Custom weather rendering in METAR Mode. Addressed issues in the METAR parsing pipeline, including interpolation logic and fallback handling, preventing incomplete or partial scene generation. FIXED – Custom weather rendering in Simple Mode. Corrected slider-based parameter translation and rendering callbacks. FIXED – Custom weather rendering in Advanced Mode. Rebuilt several internal hooks responsible for multi-layer atmospheric rendering, improving fidelity and proper synchronization between volumetric clouds, and lighting. FIXED – Required description field preventing preset saving and edit function. Adjusted UI rules to allow preset persistence without unnecessary conditions. FIXED – UI validation preventing the Save button from enabling. Resolved conditional flag errors that interfered with save-state logic. FIXED – GetLocalSettingsRead() not reading local settings.json. Repaired the file read routine, corrected its directory resolution, and improved JSON parsing, ensuring user preferences load correctly at startup. FIXED – Spelling correction of “Enviro” in the save dialog box. Corrected text label. ADDED – Startup Log System for application process verification. Integrated a multi-stage logging pipeline that records initialization events, module load order, environment checks, and error flags. ADDED – Simulator Runtime Validation. Implemented a detection function to confirm whether Microsoft Flight Simulator is actively running. This ensures correct sequencing, prevents null-reference operations, and delivers safer startup behavior.

December 26, 2025Dec 26 "FIXED – Custom weather rendering in Simple Mode. Corrected slider-based parameter translation and rendering callbacks." Really? I have Atmos for 2024 and love it, but is it possible to have some of these descriptions in plain English please? Rob (but call me Bob or Rob, I don't mind).

December 26, 2025Dec 26 a joke that this "changelog" took so long. What about the crappy interface ? Carsten U

December 28, 2025Dec 28 I get a lot of cloud flashing on occasion when using Atmos. I have been using it since SU4 Beta release came out and it seems shader related to me. It usually lasts for 10-15 seconds and if I shut off Atmos while it is happening it stops. I posted on the Discord but maybe I am the only one with the issue. It happens with any of the presets I have used and one that I created. It is pretty random and doesn't happen on every flight. Not sure if there is one particular setting that causes the problem or not... Eric i9-12900k, RTX 5070ti OC, 32GB ddr5 5600 RAM, 2TB 980 Pro SSD, Titan 240RX AIO, Samsung CRG90 49", Win 11

December 29, 2025Dec 29 Well, missed that then, reinstalled Atmos last week after long time away from the sim.

December 29, 2025Dec 29 Not on Just Flight yet it seems. I guess I'll just have to wait until they update the installer?
