Insydium unveils NeXus

Insydium unveils NeXus

Saturday, September 17th, 2022 | Posted by Jim Thacker

NeXus, Insydium’s upcoming GPU-accelerated particle simulation toolset for Cinema 4D, shown running on a high-end Windows desktop with a 16-core Core Intel i9-12900KS CPU and Nvidia GeForce RTX 3090 Ti GPU.

Insydium has posted a preview of NeXus, its new GPU-accelerated particle simulation toolset for Cinema 4D.

An evolution of the functionality of X-Particles, the firm’s particle-based multiphysics plugin, NeXus is described as “the first wave of cross-platform GPU-powered X-Particles tools”

It will be available via the upcoming update to Insydium’s Fused product collection.

X-Particles: a versatile particle-based simulation tool for motion graphics and VFX work
First released a decade ago, X-Particles has become an essential part of many Cinema 4D artists’ tookits, for creating complex effects for motion graphics and visual effects work.

Beginning as a pure particle effects plugin, its feature set has steadily broadened to encompass a range of particle-based simulations, and now includes smoke, fire, liquid, granular fluid, cloth and dynamics toolsets.

With NeXus, Insydium has begun to move those tools to the GPU, with the firm descring it as “the first wave of cross-platform GPU-powered X-Particles tools”.

The toolset includes three GPU-based solvers, nxFluids, nxFoam and nxConstraints – not surprisingly, for liquids, foam and simulation constraints.

nxFluids includes both PBD (Position Based Dynamics) and SPH (Smoothed Particle Hydrodynamics) solvers, the latter capable of granular fluid as well as liquid simulations.

The main benefit over their CPU-based equivalents in X-Particles is “massive speed improvements”.

Insydium doesn’t put a figure on the speed boost, but in the video above, simulations are visibly faster when running on the GPU, with users able to interact with at least simple systems in the viewport in real time.


NeXus also includes 14 general-purpose GPU-based particle modifiers, shown in the screenshot above.

As well as speed improvements over their CPU-based “cousins”, some include new functionality, with the turbulence modifier getting new controls for Persistence and Lacunarity.

Available as part of Insydium’s Fused product bundle
Since we last wrote about X-Particles, Insydium has changed the way that its software is licensed, ditching the old individual product licences in favour of Fused, its all-in-one bundle of Cinema 4D tools.

It isn’t entirely clear from Insydium’s description whether NeXus will be a part of X-Particles itself, or a separate product within the Fused collection.

When the question was posed directly in the YouTube comments to the sneak peek video, the firm replied: “NeXus has been written from the ground up to be a GPU particle simulation system. It will be available to all customers with a Subscription or a license in Maintenance.”

We’ve contacted Insydium to see if we can get a clarification, and will update if we hear back.

As well as X-Particles, Fused includes procedural modelling toolset MeshTools, terrain generator TerraformFX, plant generator Taiao, and renderer Cycles 4D.

Pricing and availability
NeXus will be available as part of the Summer 2022 update to Fused in the “next few weeks”.

New perpetual licences of Fused cost £750 ($1,072.50). Rental costs £348/year ($497.64/year). Prices exclude tax. The update will be free to users with current maintenance contracts.

The Fused plugins are compatible with Cinema 4D R19-S26, running on Windows 7+ and macOS 10.13+.
