--- title: "4.18.2 LTS Windows" canonical: "https://documentation.chaos.com/space/ERN/1109065731/4.18.2%20LTS%20Windows" format: markdown --- Release Notes 24.06.2026 ## **Improvements** --- - **New Interface Design:** Enscape's interface has been rebuilt on the Chaos design system, giving a cleaner and more modern look while keeping your workflow familiar and consistent with the rest of the Chaos family. - **Chaos Notification Center:** Stay informed directly within Enscape with in-app notifications for tips, feature updates and important messages, reachable from a dedicated inbox in the renderer toolbar. Notifications can be snoozed for an hour or until the next day, and the old update popup has been retired. - **Enscape to Envision Live Link:** Continue your work in Envision with a one-click handoff from the CAD toolbar, with no manual export, making it easier to create high-end animations and cinematic visuals. - **Complex Scene Support:** Removed the 2 GB scene size limitation, so Enscape can handle larger and more complex projects without serialization-related crashes. - **Revit 2027 Support:** Enscape now supports Revit 2027, including its new texture search paths, so materials resolve correctly and your workflow stays uninterrupted when you upgrade. - **Improved Asset Brush Placement Speed:** Placing assets with the brush is now significantly faster and more stable. - **Consistent Light Clustering:** Light Management now uses the same clustering algorithm in all visualization modes, so behaviour no longer changes between viewing all lights and only visible lights. - **Intuitive Asset Scaling:** The scaling gizmo now behaves more intuitively. Scaling along the X and Z axes follows the direction you move your mouse, whatever the gizmo's orientation. - **Asset Brush Distribution:** Assets are now distributed more uniformly during brush placement, and density is handled correctly when overlap is allowed at maximum density. - **Impact:** “Peak Loads” has been renamed to “Peak Energy Demands” to align with IES terminology. - **Help Panel:** The mode-specific tab is now selected automatically when a GUI mode is activated or changed. - **Grass:** Smoother transition between detailed grass and LOD grass, reducing visible cut-offs especially in orthographic views. - **Scene Export:** The enabled and disabled state of lights is now included when exporting .vrscene files, so lights you switched off stay off in the exported scene. - **Asset Library:** Enscape now finds the correct Cosmos Browser instance on shared machines, so the Asset Library connects reliably when several users are logged in. - **Chaos Cloud:** Uploads now correctly handle scenes with textures that use Unicode characters. - **Security Update:** Updated log4net due to a vulnerability issue in 3.2.0. - **AI Enhancer:** The AI Enhancer feature is no longer in beta. - **Impact:** Energy and carbon results now switch units dynamically between kWh, MWh and GWh, kgCO₂ and tCO₂, and their imperial equivalents, instead of using rounded “1K” and “1M” shorthand. - **Envision Live Link:** Archicad and Rhino now have their own Start Envision Live Link button, with Live Updates and Camera Sync, and finalized localized labels. - **Chaos Notification Center:** Toasts and modals no longer appear while the notification inbox is open, so they cannot interrupt you while you are reading. - **Chaos License Server:** Updated to 6.3.1, adding PAC-file proxy support for enterprise networks. - **Chaos Unified Login:** Fixed the “database is locked” error when several Chaos applications register at the same time, and added a Windows system tray icon and a graphical installer. - **Scene Export:** Improved the speed of the full scene export. - **Localization:** Refreshed the Enscape and Notification Center translations. ## **Fixed Bugs** --- - **Light Management:** Fixed lights positioned behind geometry briefly appearing when opening the Light Management window. - **Asset Library:** Fixed Enscape freezing when the Asset Library hotkey was pressed repeatedly. - **Asset Brush:** Fixed “Preview Selected Area” and “Confirm Placement” becoming disabled after distribution changes. - **Material Editor:** Fixed the Material Editor not always updating the Height Map Type when changing materials. - **Material Editor:** Fixed the Material Editor UI becoming stuck when the current material cannot be saved. - **Custom Asset Library:** Fixed custom assets becoming corrupted when saving failed due to file access permissions. - **Ray Tracing:** Fixed ray-traced artificial lighting not working properly with clearcoat materials when using ReSTIR. - **Ray Tracing:** Fixed a hardware ray tracing issue where block artifacts could occur in low-light reflections. - **Ray Tracing:** Fixed an occasionally wrong normal direction. - **Impact:** Rooms with very low heights are no longer included in the Energy Use Intensity calculation. - **Telemetry:** Fixed the “Learn More” link on the Telemetry page not opening the help page. - **Veras:** Fixed the Veras file save dialog omitting the file extension in certain conditions. - **Revit:** Fixed faulty materials causing the entire material feature to stop working. - **Revit:** Fixed renamed Cosmos assets not being placed in the same family as previous instances. - **Archicad:** Fixed cases where Enscape would not be registered during installation, including Archicad 29. - **Envision Live Link:** Fixed the camera sync state not being updated in the Envision Live Link menu. - **Envision Live Link:** Fixed errors when starting Envision Live Link caused by missing UVs in the CAD geometry. - **Envision Live Link:** Fixed the Live Camera not being set up in Envision when the initial Revit camera had no field of view. - **Envision Live Link:** In-CAD view selection in Revit is now disabled while Envision is running, until wider view support arrives. - **Vectorworks:** Fixed asset creation being affected by the active working plane of the project in Vectorworks 2026. - **Asset Library:** Fixed Enscape repeatedly showing the same message and never closing if the CAD was closed during multi-asset placement. - **Selective White Mode:** Fixed Revit RPC objects not respecting the Selective White Mode filter when Invert was enabled. - **Rhino:** Fixed symbolic links in file paths not being automatically resolved. - **Revit:** Improved stability in Revit when using Live Camera, preventing a potential crash while moving the Enscape camera. - **Stability:** Fixed exceptions being incorrectly turned into generic IPC serialization errors. - **Visual Settings:** Fixed a crash when opening Visual Settings or the Video Editor. - **In-App Prompts:** Fixed Veras and Envision prompts not being permanently dismissible. - **Batch Rendering:** Fixed a crash when canceling batch rendering while Light Management was active.
