Developer Michael Venous has launched the Fumaris extension for Blender, a two-part software package that shifts simulation tasks from the CPU to the GPU. It aims to bypass the traditionally slow baking times associated with existing workflows.
Why it matters
By leveraging NVIDIA's Flow solver, this tool offers a significant alternative to Blender's Mantaflow framework. It reduces reliance on slower CPU-based calculations to improve performance for 3D artists.
The Fumaris extension requires Blender 5.2 or higher and supports Windows, Linux, and macOS. It uses a sparse grid for calculations and transmits simulation data as a raymarched viewport-sized image.
The players
Michael Venous
Michael Venous is the software developer who created the Fumaris extension.
Blender
Blender is an open-source 3D computer graphics software suite used for modeling, animation, and rendering.
The details
Fumaris consists of a Python add-on for UI and scene export paired with a native runtime that performs GPU-based simulations. The output remains compatible with OpenVDB and native Blender volume rendering systems.
Timeline
October 21, 2026: The extension was officially released.
The Tech Race
The Fumaris extension challenges the established Mantaflow framework by migrating heavy computational tasks to the GPU. This shift signals a broader move toward hardware-accelerated workflows in 3D animation software.
Users can expect faster simulation baking times when working with large volumes in Blender. The extension allows artists to maintain compatibility with existing volume rendering tools while utilizing more powerful GPU hardware.
The takeaway
Artists looking to optimize their rendering pipelines should consider testing GPU-accelerated solvers to reduce downtime. Adopting these specialized tools can significantly streamline complex 3D projects that were previously bottlenecked by CPU performance.
