Earns its place in the superhive library as a physics addon built by a former Walt Disney Animation Studio simulation developer, pairing a unified multi-physics solver with intersection-free guarantees.
HiPhyEngine is a multi-physics simulation engine for Blender, developed by a former simulation software developer from Walt Disney Animation Studio. It simulates rigid body, hair, cloth, and soft body in a single unified, fully-coupled solver that guarantees intersection-free results, and it includes an MPM solver that brings snow and sand simulation to Blender.
Compared to Blender's internal physics, which uses position-based dynamics with a mass-spring system and discrete collision detection, HiPhyEngine uses finite element discretization with continuous collision detection. The developer states this produces more physically accurate results and intersection-free collisions, even with complex, multi-layered collisions and regardless of how fast or how thin an object is. The finite element approach is resolution independent, so lower-resolution simulations used for parameter tuning keep the same large-scale behavior at higher resolution.
Most simulation parameters can be animated and mapped, and the addon integrates with the SeExpr2 expression language for creating force fields and attributes. It is parallelized and vectorized to use all CPU cores. Version 1.1.1 added support for Blender 5.1.
Hiphyengine is best for blender artists building multi-physics simulations that couple cloth, hair, rigid body, and soft body while needing intersection-free results.
Hiphyengine is completely free to download and use.
HiPhyEngine added support for Blender 5.1 in version 1.1.1, and it works with both the VFX2025 and VFX2026 platforms. Blender 5.1 moved from the VFX2025 platform to VFX2026 and updated its Python version from 3.11 to 3.13, and version 1.1.1 accounts for that change. For the full list of supported Blender versions and any additional requirements, check the developer's page, since compatibility details can shift as new releases arrive.
HiPhyEngine uses finite element discretization with continuous collision detection, while Blender's internal physics uses position-based dynamics with a mass-spring system and discrete collision detection. The developer states this makes HiPhyEngine's results more physically accurate and guarantees intersection-free simulation, even with complex, multi-layered collisions and regardless of how fast an object moves or how thin it is. The finite element approach is also resolution independent, so a lower-resolution simulation used for parameter tuning keeps the same large-scale behavior when you raise the resolution.
HiPhyEngine offers a six-month trial, giving you time to fully experience the engine before making a purchase. Once purchased, you can keep using the current version indefinitely and gain access to one year of feature updates. This catalog lists the entry as free, so for current pricing, licensing terms, and details on how the trial and updates work, check the developer's page, where the most up-to-date information is maintained.
HiPhyEngine includes an MPM solver that brings snow and sand simulation to Blender. Beyond that, it simulates rigid body, hair, cloth, and soft body in a single fully-coupled solver that handles the interactions between these material models without extra setup. It covers five different material models in one unified engine, so coupling cloth with rigid body, cloth with hair, or soft bodies is managed by the solver itself. For a look at these simulations, a demo video is available.
HiPhyEngine is parallelized and vectorized to fully utilize all CPU cores, and the developer states that even with complex collisions, each frame takes only seconds. The engine is designed for performance alongside full artistic control, and most simulation parameters can be animated and mapped. In Blender, you can use attributes and geometric nodes to build animated simulation parameter maps, and there is integration with the SeExpr2 expression language for creating force fields and attributes.
