Changelog

What has changed in NeXus for Blender, newest release first.

NeXus keeps itself up to date from the Updates section of the add-on preferences, covered in Installation and Licensing. Only changes from the 2026.0.0 release onward are listed here.

2026.1 Beta 3

Public beta, 30th October 2026

Items marked Blender or Cinema 4D are for that host only. All the others are in both hosts.

Added

nxSpawn: spawns new particles from existing particles, with Direction, Pulse mode and signed Speed.
nxFluid2D: a realtime 2D fluid that runs in the UV map of a surface.
nxScatter: places points over the selected meshes, with Object Alignment and object transforms.
nxSystem: a ready-made folder set in the NeXus Hierarchy. (Blender)
nxSystem: a new object that builds the NeXus folder hierarchy. (Cinema 4D)
nxFalloffMap: writes falloff layers into vertex map or vertex color tags. (Cinema 4D)
#9139 nxConvert: replaces X-Particles emitters and groups with NeXus ones. (Cinema 4D)
#9128 NeXus modifiers can now drive X-Particles emitters. (Cinema 4D)
Import and export of Cinema 4D scenes (File > Import and File > Export), with meshes, curves, cameras, lights, NeXus objects and Cycles 4D materials. X-Particles emitters and groups can convert to NeXus. (Blender)
nxEmitter: emits from the points of point cloud objects. (Blender)
nxEmitter: emits from Gaussian splats and can output a splat object. Needs Blender 5.3 or later. (Blender)
nxEmitter: emits from Blender particle systems. (Blender)
nxEmitter: Start setting for Liquid Fill, so the fill can begin after frame 1. A Liquid Fill saved in Beta 2 keeps its saved Start, frame 2 by default. (Blender)
nxCache: new Alembic (Single File) format that writes the whole cache into one file.
nxCache: new PLY format.
#9355 nxCache: Local Coords option, so the cache moves and scales with the nxCache object.
nxFalloff: new Wet, Curvature and AO modes and a Blur layer in the nxFalloff Modifier. They work in vertex maps.
#8604 nxFalloff: Noise Frequency on the Grow layer.
nxExplosiaFX: Domain Space setting, so smoke can stay in world space.
#8907 nxOcean: Beach, Swash and Surf controls, with Sand Grain, Clearing Depth and foam that strands on the beach.
nxOcean: bow sheets, waves that reflect off colliders and waves that slow near the shore.
nxMPM: new Snow, sticky preset for snowmen and snowballs.
#8801 nxEmitter: Stick to Source option.
#8526 nxCollider: Attraction and Repulsion settings.
#9096 nxMesher: Camera and Target links for UV projection.
#9130 nxWarp: Wind is now a moving wave with gusts. It has new Size, Frequency, Seed, Direction and Flag settings. Its Speed setting is gone. Frequency is now in waves per second.
#9151 nxWarp: Flow Speed control.
#9204 nxWarp: Reach control for Flow mode. At the 0% default a Flow warp no longer pulls in particles from beside its cage. Beta 2 Flow scenes may need Reach raised. 300% gives the Beta 2 behavior.
#9181 nxGroup: gradient controls for Gradient color mode.
#9299 nxGroup: noise controls for Noise color mode.
Preferences: Compute Device picks the GPU that runs the simulations. It can be a different GPU from the one that draws the viewport.
Preferences: Precompile Shaders option with a manual button.
Help text for every parameter.
nxShatter: breaks a list of objects at once, each with its own full Pieces count. The list replaces the single Source. Hide Source is now Hide Objects. In Cinema 4D it also breaks the objects under it.
nxScatter: the Help button opens the nxScatter page.
#8491 The HUD visibility of each view is saved with the file. (Blender)
#8498 #8499 NeXus Hierarchy: deactivated rows can be renamed, and new objects go in the selected folder. (Blender)
#8562 Particles can be seen through objects in X-Ray. (Blender)
#9395 nxBioLogic: drag handles for the Grid Size domain. (Cinema 4D)
nxBioLogic: a Resolution setting for the domain. (Cinema 4D)

NeXus is now in Cinema 4D too, as a public beta with the same features. See NeXus for Cinema 4D. For a short tour of the new features, see What’s New in the Beta. Items marked Blender or Cinema 4D are for that host only. All the others are in both hosts.

Added

New objects

nxMPM: a multi-material solver for liquid, elastic, snow, sand, brittle, metal and foam materials, with a Materials list, presets, auto sleep and grid fracture.

nxDeformer: drives a mesh from particles, with Standard, Breaking and Remesh modes and tearing.
nxPin: holds selected particles still, as anchors.
nxBind: holds particles in place inside a deforming volume, then releases them.
nxBioLogic: particle-based cellular growth with generated tubes.
nxFalloff Modifier: a falloff layer that reshapes the falloffs below it.
Vertex Maps: write falloffs onto a mesh as attributes or vertex groups.

Emitter

nxEmitter: Display Channels and an Initial State tab. Pulse emission gets Mode and Match Solver Resolution. The Gradient gets Solver Material and Solver Blend parameters.
Collection Instances work as emitter sources, in every mesh-input modifier and as colliders.

Simulation

nxFluids FLIP/APIC: Wall Friction, Resolution, Recolor Particles By, non-Newtonian liquids (Flow Index, Yield Stress) and variable Liquid Density in the Mixer.
nxCollider: Adhesion (with Stick Distance), per-parameter Variation and Map By surface mapping, Draw Bounds and a Global toggle.
nxFoam: Adhesion and Foam Location. nxFoam and nxSheeter get a button that creates the output emitter.

Generators

nxGenerator: Mode (Sequentially, Randomly, Choose by Index) with Object Index. Its settings are split into General, Transforms and Color tabs.
nxCache: a record frame range and Disk Reserve, which stops caching with a warning when the drive is nearly full.

Forces and particle

nxColor: a Cyclic layer and a Channel pick. nxFlowField: a Cyclic layer.
nxDendrite: a per-layer Change Color switch plus Speed Reduction and Plane Angle for Curl.
nxCover: spline Thickness for the Ray operation.
nxQuestion: Asleep and Bound flags and Sleep and Bind actions. Set Color can pick a Display Channel.

Systems

nxFalloff: new shapes (Attribute, Box Frame, Capsule, Cone, Cylinder, Object, Points, Spline and Torus) plus a Falloff list on every layer of a layered modifier.
Mapping: one layer can drive several destinations, read a chosen Display Channel and pick an nxMPM material row.
Adding NeXus Objects: the Add menu is split into Presets, Generators, Dynamics and Modifiers submenus.
Preferences: the Accelerated Viewport section says why it fell back, lists what draws on the CPU and has a Retry Accelerated Viewport button.
nxQuestion gains a GLSL script editor. Quill can use your own AI provider. (Blender)
Windows ARM64 is now supported. (Blender)

Cinema 4D

NeXus for Cinema 4D: rebuilt on the same engine as NeXus for Blender. One license covers both hosts.

FLIP and ExplosiaFX solid voxels draw more clearly, especially on 4K displays.
NeXus icons replace the built-in Blender icons on many controls.
nxColor layer Strength works as an opacity, not a per-frame rate.
nxEmitter: Plane is hidden for 3D shapes. An assigned object defaults to polygon area emission. A curve source offers only Points and Edges. The Pulse rate is the rate during the pulse.
nxCache: Auto is now Auto Frame Range, Time to Complete is removed, the Group is recorded by default and cached particles interpolate between cache frames.
nxGenerator: Spawn is now Bias. Source Emitters is now Emitters.
nxGroup: the Shader and Object Color color modes are removed. They had no effect.

2026.0.1

Released 16th July 2026

Added

Per-emitter particle count in the viewport HUD. With Particle Count enabled in the HUD tab, a new Per Emitter toggle breaks the total down per emitter, listing each emitter by name with its own count. See NeXus Hierarchy.
Motion blur for generator instances. In Geometry mode, nxGenerator instances now pick up native motion blur in EEVEE and Cycles, following each particle across the shutter. See nxGenerator.
Filter the particle console by emitter. A new toolbar dropdown narrows every readout to a single emitter. Leave it on All Emitters for the whole population. See Particle Console.
