Release Notes 08.10.2025


## **New**

---

- **Save as External Model for Enscape Returns to SketchUp: **The “Save as External Model for Enscape” feature is back in SketchUp. This powerful workflow lets components be saved as lightweight external files (Linked Models), improving project performance by replacing detailed models with wireframe placeholders inside SketchUp. Once loaded in Enscape, the full geometry appears in real time. After a temporary removal due to bugs, it’s now reintroduced with improved stability.

- **Revit Improved Scene Hierarchy Naming for .vrscene Export: **Improved scene hierarchy path exported to .vrscene files to align with Enscape’s BIM Mode naming. The unique element ID is no longer appended, resulting in cleaner and more consistent paths (e.g., Walls/Basic Wall/Generic - 200mm). This improves readability and consistency across exported scenes.
- **Vectorworks 2026 Support:** We’ve added support for Vectorworks 2026.


## **Fixed Bugs**

---

- **Error logs:** Fixed very large logs when many scene elements are affected by the same error.
- **Rhino View management:** Fixed not being able to cycle through Favorite Views in Rhino 8 using keyboard shortcuts.
- **V-Ray scene export:** Added path length check before V-Ray scene export.
- **V-Ray scene export**: Fixed not being able to export V-Ray scenes when assets failed to download.
- **Asset library: **Fixed loading indicator being visible in thumbnail when editing asset variants.
- **Asset library:** Fixed Enscape license not being released after the CAD Asset Library is closed.
- **Sound source:** Fixed sound source position update being delayed in the viewport.
- **Software Ray Tracing:** Stabilized frame rate when using SWRT.
- **Impact settings:** Fixed the location search box in the impact settings panel losing focus when the last character was deleted.
- **Batch rendering:** Fixed panorama batch render order to be consistent with image batch render order.


## **Known Issues**

---

- **Enscape crashes in (heavy load) captures: **Crash in PathTrace.glsl may occur under high GPU loads when rendering large screenshots (e.g., 4K with artificial lights or 6K without artificial lights).
- **Asset library: **Assets are completely missing for some users.
- **Vectorworks 2026:** Changing texture field for data visualization shuts down Enscape and Vectorworks. The Vectorworks team is also working on the issue.
