Optimization in Brush Evaluation in Blender

Published on January 08, 2026 | Translated from Spanish
Blender improves brush evaluation with faster processing, less latency, and greater efficiency in complex models, optimizing the sculpting experience.

The recent optimization of the sculpt mode in Blender has significantly improved the software's performance, allowing for smoother interaction between brushes and the mesh. With reduced latency and greater processing efficiency, artists can now work with greater precision and without interruptions.

Problems in Brush Evaluation in Previous Versions

Before the optimization, brush evaluation in Blender was performed sequentially and by processing each individual vertex. This approach had several drawbacks:

"Improving brush evaluation means reducing wait times and enhancing creativity in digital sculpting."

Restructuring of the Evaluation Process

To improve efficiency, a new system has been implemented in which brushes process multiple vertices in organized blocks within BVH nodes. This change has enabled:

Fewer Redundant Calculations, More Speed

One of the main problems in previous versions was the amount of unnecessary calculations performed with each brush application. Now, with segmented evaluation in optimized blocks, redundant processes have been eliminated, achieving:

Use of SIMD and Improvement in Cache Memory

The optimization in Blender has also included the use of SIMD (Single Instruction, Multiple Data), a technique that allows multiple calculations in parallel across several vertices. Additionally, access to cache memory has been reorganized to:

Impact on User Experience

Thanks to these optimizations, brushes in Blender now respond more fluidly, eliminating perceptible delays even on models with millions of polygons. This allows digital artists to focus on their creativity without technical interruptions.

A Key Advancement for Digital Sculpting in Blender

The optimization in brush evaluation not only improves performance in the current version but also establishes a solid foundation for future advanced tools. With more efficient and precise processing, Blender continues to solidify itself as one of the most powerful options for digital creation.
