3D software Blender 5.1 refines key workflows, boosts performance & expands geometry nodes

Blender 5.1 is now available, marking the latest update to the open source 3D creation suite. This release centers on refinement across the pipeline, balancing feature additions with bug fixes to enhance stability and efficiency for its wide user base.

Among key workflow improvements, Grease Pencil introduces a fill system that supports holes, while both curves and text benefit from a more intelligent rendering algorithm. In parallel, rendering, animation, and the viewport receive considerable performance upgrades, making interactions smoother and more responsive.

Following these visual enhancements, geometry nodes gain new capabilities, particularly with volume support and improved string handling, significantly aiding technical artists. The shading system is also extended by a Raycast node targeted at non-photorealistic rendering scenarios.

Building on this, the compositing, video sequencer, modeling, and snapping tools undergo several refinements. These updates are accompanied by hundreds of bug fixes and optimizations that make Blender 5.1 faster and more reliable for production work.

Finally, to improve future compatibility, many of Blender's core libraries have been updated to meet the VFX Platform 2026 specification, most notably advancing Python scripting support to version 3.13.
