V-Ray for Blender Update 4.1 is out

V-Ray V-Ray for Blender Announcements

Hello everyone,

V-Ray 7 for Blender Update 4.1 is out now.

In this release we introduce rendering and relighting of Gaussian Splats, Chaos Scatter (available as an additional addon with V-Ray) as well as Live Link to Chaos Vantage for realtime rendering and previews.
For best interoperability with other V-Ray integrations like 3DS Max, Maya, Cinema 4D, etc we’ve added an option to import V-Ray Scene Files (.vrscene) as native objects in Blender. This means that any material or object from other V-Ray integrations can now be transferred in V-Ray for Blender as long as there is an alternative in Blender for it.

The tools in V-Ray for Blender are also growing up with two new tools - The Material Manager and the V-Ray Object Lister.

Changes and new features apply for both the Community Edition and the Commercial Edition of V-Ray for Blender.

Download the latest build from our website and check the Documentation page for more information and resources.

Amazing update! :clap: Huge thanks to the team for the work on Chaos Scatter and especially the native .vrscene import. This is a huge step for V-Ray for Blender and makes cross-V-Ray workflows much easier. Really excited to try it! :rocket:
