INSYDIUM NeXus

Description

INSYDIUM NeXus

NeXus is GPU-accelerated particle simulation for Cinema 4D and Blender, with real-time viewport feedback and fast iteration. From fluid dynamics, fire and multi-material simulation to organic growth and constraint-based dynamics, everything runs on the GPU. One licence works in both.

Imitated but never equalled, NeXus is the original and still the best.

Simulation, reimagined

NeXus 2026.1 Beta 2 is out now, for Cinema 4D and Blender.

This is the first NeXus for Cinema 4D on the same engine as Blender, so both hosts get the same solvers, the same modifiers and the same results. It also brings our new nxMPM multi-material solver plus nxOcean, nxShatter and nxWarp, all three new in Beta 2, and a long list of upgrades.

Who gets the Beta? Any INSYDIUM licence. No licence yet? Request a free Beta licence from your INSYDIUM Customer Account.

In Cinema 4D the Beta unlocks all of INSYDIUM Fused. Any INSYDIUM licence gets full access to the INSYDIUM Fused collection, including X-Particles, Taiao, TerraformFX, MeshTools and Jidou, plus the latest NeXus Beta until the Beta closes.

Already own NeXus for Blender? Your licence now runs NeXus in Cinema 4D too, at no extra cost.

Already use INSYDIUM Fused or X-Particles? You always get 50% off.

New in 2026.1

NeXus for Cinema 4D: rebuilt on the same engine as NeXus for Blender. One licence, both hosts.
nxMPM: a new multi-material solver. Liquid, elastic, snow, sand, brittle, metal and foam materials in one simulation.
nxMPM controls: two solver modes, resolution control with a grid memory estimate, walls that can open and full nxCollider support.
nxMPM material mixer and fracture: materials change into other materials by age, speed, stretch, damage and more. Fracture lets any material crack apart.
nxMPM auto sleep: particles at rest stop computing until a collider, a force or the grid wakes them again.
nxMaterial: one click makes an emitter with an MPM material ready to simulate.
nxDeformer: the particles move and your mesh follows. It can tear where the mesh stretches too far and remesh. In Blender it can also subdivide and deform curves.
nxPin: hold selected particles still to anchor cloth, rope and soft bodies. Pick them by falloff, group, ID list, particle data or object, carry them on an object or pin them on birth only.
nxBind: keep particles in place inside a deforming volume, then release them by age, life, speed or temperature, in chunks if you like.
nxBioLogic: cellular growth with reaction-diffusion, differential growth, physarum, particle life plus coral and primordial modes, with tube meshes.
nxOcean: a GPU ocean surface with wind and wave spectrum controls, foam and whitecaps, spray, wakes from moving objects and shorelines. Objects can float on the waves and the ocean works with FLIP liquids.
nxShatter: break meshes into pieces on the GPU.
nxWarp: a new modifier that warps particles, with Scroll, Fit Parent and the NeXus noise types. Particles that leave it can be killed, moved to another group or released.
Falloffs: nine new shapes including Torus, Capsule, Cone, Spline and Attribute, plus falloff layers that invert, clamp, remap, step, quantize, curve, cycle, freeze, decay, delay or grow. Every modifier layer gets its own falloff list and there is a new nxFalloff Modifier.
Cyclic layers: repeating patterns with a Cyclic layer in nxColor and a Cyclic generator in nxFlowField.
nxEmitter Initial State: start a simulation from a saved state, kept in the scene or in a file. Keep Stored Age keeps the saved age of each particle.
nxEmitter Display Channels: several display channels you switch between, each with its own colour, that mapping can read from.
Mapping to many targets: one mapping layer can now drive several parameters.
Match Solver Resolution: every emitter can now match the solver resolution.
nxQuestion: Set Sleep for nxMPM particles and an Asleep flag.
FLIP liquids: thick, non-Newtonian liquids, liquid density in the mixer, wall friction and colouring by viscosity or density.
nxCollider: adhesion with Stick Distance, Creep, Pull, Escape Speed and Stringing. Variation now also works on Bounce, Friction, Scatter and Expand. Surface maps can come from vertex maps, attributes, colour, images or noise. There is a new Outside, Fill Hollows normals option.
nxMesher: UV advection, so textures move with the liquid, plus Detail Aware smoothing and nxGroups as a source.
nxCache: record a frame range. It stops safely with a warning when the disk is full.
New viewport renderer: shared by both hosts, with improved voxel drawing for FLIP, nxExplosiaFX and nxFlowField.
Add menu: sorted into Presets, Generators, Dynamics and Modifiers.
And more: a new nxGenerator mode with tabbed settings, per-layer colour in nxDendrite, create buttons for nxFoam and nxSheeter plus spline thickness in nxCover.
Blender: Collection Instances work as colliders and in every modifier that takes a mesh. Falloffs can read vertex maps, nxQuestion gains a GLSL script editor and Quill can use your own AI provider. Windows ARM64 is now supported.
Cinema 4D: a link to the native GPU particles and Pyro in Cinema 4D 2025.3 or later, where NeXus modifiers can also drive the native particles. A NeXus Project Settings tab with document substeps plus GPU preferences and Rewind on Load.

Powered by Theron™

Theron is our GPU simulation engine. It is built on a modern Vulkan foundation with our own compute core, so nothing waits on your CPU. Simulations solve quickly, scale to high particle counts and update in the viewport while you work.

Vulkan is why it runs where you do: NVIDIA, AMD and Intel on Windows and Linux plus Apple Metal on macOS. You get the power of a low level compute platform without being tied to one GPU vendor.

One engine, two hosts. NeXus for Cinema 4D and NeXus for Blender run on the same Theron engine, so a setup behaves the same way in both. Your experience and your training carry straight over. What changes is how you add things and wire them up in each host.

Works with Cinema 4D's own GPU particles and Pyro. In Cinema 4D 2025.3 or later, NeXus links straight into Cinema 4D's native GPU particles and Pyro. NeXus sends its particles into Cinema 4D's GPU particles and reads them back. nxExplosiaFX and Pyro exchange smoke and fire both ways, so your native Cinema 4D setups and NeXus work together in the same scene.

Licensing

NeXus is a perpetual licence from a one off payment. Your licence never expires and it works in both Cinema 4D and Blender.

Twelve months of updates. Your purchase includes a 12 month support period from the day you buy. We ship new features and fixes all year and everything released while it runs is included at no extra cost.
What you receive is yours to keep. Every build you get during your support period stays yours and keeps working, whether you renew or not.
We answer you either way. Our support does not switch off when your support period ends. Ask us anything, any time.
Renewing is optional. To keep receiving new builds, renew for another 12 months at half the full price at the time. No subscription, nothing renews on its own and nothing is charged unless you choose to.

An INSYDIUM Customer Account is required for your licence and downloads. If you do not have one yet, create a Customer Account to get started.

One system, one workflow

No single solver is right for every shot, so NeXus has four for liquids and granular material: PBD, SPH, FLIP and APIC. Now there is also MPM for mixed materials that bend, break, pile up and melt. Alongside them sit a full volumetric solver for fire, smoke and explosions, a particle solver and over 40 modifiers covering emission, forces, motion, collisions, growth, meshing and per particle logic.

The liquids, granular material and secondary particles share one particle system, so the parts work together. Foam reads the liquid solver's own surface field rather than guessing from a bag of points. The volumetric solver both feeds off those particles and drives them, so one turbulence force can shape your liquid and your smoke from a single set of settings.

All of it lives in one plugin, inside Cinema 4D or Blender. One purchase, one licence, one workflow and one place to ask for help, instead of collecting tools that each solve a piece of the job.

System Requirements

Cinema 4D: Cinema 4D R19 or later. The link to Cinema 4D's GPU particles and Pyro needs Cinema 4D 2025.3 or later.

Blender: Blender 4.3 or later. Every version from 4.3 onwards is supported, including Blender 4.5 LTS and Blender 5 and newer. NeXus for Blender is installed via the Blender Extensions platform, which was added in Blender 4.3.

NeXus is GPU-accelerated, so you will need a modern GPU with up-to-date drivers and at least 4GB of VRAM. On Windows and Linux this requires Vulkan 1.3. On macOS it requires Metal 3.

NeXus uses online licensing. It contacts our licence server to check your licence, so you need an active internet connection to activate it and to run it. This is not an offline product.

Operating System

Windows: Windows 10 or later, 64-bit. Windows on ARM is supported in Blender. You also need the Microsoft Visual C++ 2015-2022 Redistributable (x64), which most machines already have.
macOS: macOS 13.0 (Ventura) or later, on Apple Silicon and on Intel Macs with a Metal 3 GPU. The accelerated viewport needs macOS 26.4 or later in this beta. On Intel Macs, Blender itself stops at 4.5 LTS.
Linux: glibc 2.31 or later, for example Ubuntu 20.04 LTS. Linux is supported in Blender only, as Cinema 4D does not run on Linux.

Anonymous Usage Statistics

INSYDIUM NeXus sends Anonymous Usage Statistics. You can turn this off in the NeXus preferences, unless your licence plan requires it. The statistics gathered are entirely anonymous; no personal information is stored.

The Python add-on layer of NeXus for Blender is GPL-3.0-or-later. It drives a proprietary compiled simulation engine.
