Blender News

Valve recently changed how applications run on Linux/Steam. It now defaults to run applications inside a Steam Linux Runtime. This can cause issues in Blender, such as crashing when rendering with Cycles on a GPU.

Please take a look at the Blender documentation how to workaround these issues for now. We are looking into a better solution for the future.

Happy Blending!

Blender Foundation and the online developers community are proud to present Blender 4.3!



Blender 4.3 builds on the feature-packed 4.2 LTS with improvements to existing tools, performance enhancements, and the foundations that will shape the years to come.



Some highlights:

• EEVEE: Light & Shadow Linking
• Rendering: Metallic BSDF, and new Gabor Noise texture.
  
• Compositor: Support for EEVEE passes, new White Point Color Balance, and more.
  
• Grease Pencil: Complete rewrite to support Layer Groups, Geometry Nodes, better erase tool, gradients, and much more.
  
• Geometry Nodes: For Each Zone, Gizmos, Bakes can be packed now, new nodes and UI improvements.
  
• Sculpt: Major refactor under the hood to improve performance.
  
• UV: New “Minimum Stretch” (SLIM) unwrapping method.
  
• Modeling: Bevel modifier can now use custom attributes.
  
• Brush Assets: All brushes are now assets, to be shared easily between projects.
  
• USD: Support for exporting Point Clouds.
  
• glTF: Draco mesh compression for importing, better export of UDIM tiles, quaternions and matrix attributes. Plus loads of bug fixes.
  
• And so much more!
