Release Notes 26.02.2025


## **New**

---

- **Emissive Materials as Ray-Traced Light Sources:** Emissive materials now behave as true light sources when hardware ray tracing is enabled. This ensures more predictable lighting, reduces noise artifacts, and removes the need for inefficient modeling workarounds (e.g., manually placing thousands of light sources).
  - Cleaner, more consistent lighting behavior across all emissive materials.
  - Enhanced filtering and sampling methods minimize noise and ensure efficiency in both small and large-scale projects.
  - Matches the behavior of analytical and mesh lights for greater realism.

*Please Note: This feature requires hardware ray tracing.*

- <span style="color: #000000">**V-Ray Scene Export - Export Site Context Geometry: **</span><span style="color: #000000">Now when exporting a V-Ray scene, the site context included in the scene will be exported as well.</span>
- <span style="color: #000000">**[Enscape Impact] Expanded Building Type Support: **</span><span style="color: #000000">Enscape Impact now supports additional building types, including </span><span style="color: #000000">**Hospitality, Industrial, Retail, Sports, Transportation, and Warehouse**</span><span style="color: #000000">. This expansion allows users to perform more relevant energy and comfort analyses tailored to their specific project needs.</span>




- <span style="color: #000000">**Announcement - Phased Removal of Old Host Versions: **</span><span style="color: #000000">Starting in 2025, we will remove unsupported host application versions from our installer three months after their official end-of-support announcement. While we’ve historically included older releases (</span><span style="color: #000000">*for example, the latest Enscape version can still be installed for Revit 2015 - 2021, even though these versions are no longer officially supported*</span><span style="color: #000000">), we’ve found that continuing to bundle out-of-date versions creates additional complexity for both developers and customer support teams. Since these older releases are no longer supported by their original publishers, phasing them out from our latest installers helps us focus on providing the best possible experience for current versions.</span>

<span style="color: #000000">Each time we officially support a new host application release, we’ll clearly communicate which older versions will be removed, and when, through our Forum and Release Notes. We understand change could be inconvenient, but this policy ensures better code quality, a streamlined installer, and improved support for you. Stay tuned for more details!</span>
