For those who don’t know the tool: NeXus is INSYDIUM’s GPU particle and simulation system. The new edition runs inside Blender, while the established version belongs to the X-Particles and Fused ecosystem for Cinema 4D.
Blender gets the GPU toys
NeXus for Blender has entered beta as a native GPU-accelerated particle and simulation system. It covers particles, liquids, granular materials, smoke, fire, flocking, constraints, spreading effects, meshing, trails and instancing inside Blender. INSYDIUM rebuilt the system for Blender rather than presenting the Cinema 4D edition through a thin compatibility layer. The workflow uses Blender objects and installs through the Blender Extensions platform introduced with Blender 4.3.
The software targets rapid iteration through continuous viewport feedback. Every simulation component in the beta runs on the GPU. Final speed still depends on the graphics hardware, scene complexity and solver settings, so the phrase real time remains a workload description rather than a contractual promise from the laws of physics.
Emit first, negotiate later
The nxEmitter creates particles and transfers properties from point clouds. The current beta update expands the options controlling which properties those point clouds pass into a simulation.
The emission stage connects to a sizeable collection of modifiers. nxAttract pulls particles towards a modifier or target object. nxAvoid pushes them away from specified objects. nxDrag applies aerodynamic resistance, while nxGravity supplies the familiar downward career advice.
nxExplode pushes particles away from a point. nxSplash creates an outward cone force. nxTurbulence introduces noise-driven motion, nxVorticity adds vorticity confinement and nxWind applies directional wind forces.
These tools use layered controls. Artists can combine operations inside a modifier instead of constructing every behaviour through a large node graph. Layers can carry separate values, falloffs and blending controls.
The approach keeps routine motion design accessible while retaining per-effect control. It also lowers the interface tax for artists who want to art-direct particles without turning every adjustment into a small software engineering project.
Fluids cover several arguments
nxFluids handles liquid and granular simulation through PBD, SPH, FLIP and APIC solvers. That gives artists several numerical approaches within the same broad tool rather than tying the entire workflow to one fluid model.
FLIP and APIC cover liquid simulation. PBD and SPH support particle-based fluids and grains. Controls include viscosity, density, surface tension and particle interaction. Different densities can produce different fluid or granular behaviours inside a setup.
nxUpres separates interactive work from final density. Artists can build motion with a lower-resolution emitter, then transfer it to a destination emitter with a larger particle count. This reduces the cost of experimentation before committing to a denser result.
That workflow suits effects where broad motion must settle before final particle counts, meshing and rendering. It does not remove the need to validate the high-resolution result. Increased density can reveal collisions, gaps and surface behaviour that remain hidden in a lighter preview.
Smoke and fire join in
nxExplosiaFX handles smoke and fire. Emitters can derive from objects, splines, vertex maps, shaders and particles. Controls cover particle advection, data-channel mapping and layered treatment of emitters, collisions and forces.
The system requires a modern GPU with at least 4 GB of VRAM and current drivers. That is the minimum, not a comfortable production recommendation for every fluid or volumetric scene. Dense smoke and high particle counts have never shown much respect for minimum specifications.
Motion without node archaeology
The shaping group covers a wide range of common particle operations. nxBlend mixes parameters between neighbouring particles. nxCover distributes particles across target surfaces. nxDirection layers directional control, while nxFollowGeo keeps motion travelling along surfaces or edges.
nxPush separates overlapping particles. nxRotate applies rotational force. nxScale changes geometry scale, particle radius or mass through layered operations. nxSpeed modifies velocity, and nxSpin controls particle rotation.
nxSticky attaches particles to object surfaces. nxWave creates wave motion through noise patterns. These modifiers address jobs that often begin as a simple request and finish as a graph with three frames, two reroutes and one node nobody remembers adding.
Geometry exits the simulation
nxGenerator instances meshes at active particle positions. This turns a simulated particle state into repeated scene geometry for motion graphics, debris, vegetation-style distribution and related effects. nxMesher converts particle emitters into polygon surfaces. Its role becomes particularly important for liquids, where the final image usually needs a coherent surface rather than a visible cloud of points. nxTrail produces particle trails either as a viewport overlay or as curves. The current build fixes a spline-material issue and restores trail thickness when rendering with EEVEE.
The geometry and rendering preview demonstrates this stage of the workflow, while separate official clips cover nxMesher and fluid behaviour. Together they provide a better view of the output path than the initial announcement preview alone.
Blender versions and operating systems
NeXus requires Blender 4.3 or newer. The supported range includes Blender 4.5 LTS, Blender 5 and later releases. Windows and macOS builds are available now. Linux support is coming soon. Windows and Linux require Vulkan 1.3. macOS requires Metal 3.
Online checks remain part of the deal
A customer account is required to access the beta and its licence. Licensing takes place online, so the software needs an active internet connection. The beta also sends anonymous usage statistics. Collection remains permanently enabled during the beta and cannot be disabled. INSYDIUM states that the collected statistics contain no personal information.
Perpetual means this version stays
The beta uses a perpetual licence with a one-off payment. Buyers keep the 2026 version.
All service updates for the 2026.x line are included without extra cost. Future major versions can be upgraded for half of the full price applying at that time. The licence carries neither a subscription nor maintenance fees.
The store lists a full price of £140. The current beta price is £98 excluding VAT, representing a 30 percent reduction. Owners of an eligible Fused licence can receive 50 percent off the full price. This is a paid beta rather than a free public preview. The purchase secures the perpetual 2026 licence while exposing users to software that still carries the beta label and an active repair list. But it shows that INsydium is very confident that they havea well-working tool in their box.
The model may appeal to artists tired of accumulating monthly charges for every specialised tool in the pipeline. It also places the evaluation burden directly on the buyer, since the current product remains under development.
