Release Notes 22.04.2026


## **Improvements **

---

- **Revit 2027 “Preliminary” Support:** This Enscape preview version introduces preliminary support for Autodesk Revit 2027.
- **Improved Asset Brush Placement Speed:** Placing assets is now significantly faster and more stable.
- **Consistent Light Clustering:** Light management now uses the same clustering algorithm whether you are viewing all lights or only visible lights, providing a more consistent and predictable user experience.
- **Intuitive Asset Scaling:** The scaling gizmo is now more intuitive. Scaling along the X and Z axes now correctly corresponds to the direction you move your mouse, regardless of the gizmo's orientation.
- **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/disabled property of lights is now included when exporting .vrscene files.


## **Fixed Bugs **

---

- **Light Management: **Resolved a bug where lights positioned behind other objects would briefly appear when opening the Light Management window.
- **Asset Library: **Fixed an issue where Enscape could freeze if the Asset Library hotkey was pressed repeatedly.
- **Vectorworks:** Fixed asset creation being affected by the active working plane of the project in Vectorworks 2026.
- **Revit:** Fixed an issue where faulty materials caused the entire material feature to stop functioning.
- **Revit:** Fixed an issue where renamed Cosmos assets were not placed in the same family as previous instances.
- **Archicad:** Fixed Archicad 26 being incorrectly listed as a supported version in the Enscape preview.
- **Ray Tracing:** Fixed ray-traced artificial lighting not working properly with clearcoat materials when using ReSTIR.
- **Chaos Cloud:** Fixed Chaos Cloud upload to correctly handle scenes with textures that contain Unicode characters (e.g., Chinese).
- **Impact: **Rooms with very low heights are no longer incorrectly included in the Energy Use Intensity (EUI) calculation.


## **Known Issues **

---

- **Vectorworks: **Self-referencing design layers are not rendering assets.
- **Archicad 29:** The Enscape installer may fail to register the plugin for Archicad 29.
- **Light Management - Archicad: **In Archicad, changing a light name will not update it in the Light Management window. On restart of Enscape, the new name will be shown.
