Add-on Changelog

v5.4.0 (2026-10-17)

Physics Nodes, deformable simulation and terrain authoring

  • Pro Particles Studio: the add-on, product page and documentation now use the Pro Particles Studio name. The Blender workspaces remain Pro Particles, Pro Pyro and Pro Terrain.

  • Requirements: Blender 5.0 or newer is now required. Use Vulkan on Windows and Linux, or Metal on Apple Silicon macOS. See Installation and Requirements before upgrading.

  • Physics Nodes: added the Pro Physics editor for building Particles and Pyro setups with connected Sources, Emitters, Effects, Post Effects and Outputs. Both systems can share one graph. Lists and Nodes keep separate settings; switching modes does not convert or synchronize a setup.
  • Physics Groups: build reusable, nested groups, expose controls as inputs, give each instance its own values and use groups through Blender's Asset Browser. Added particle branches, reusable Fields and Masks, and Logic loops.
  • Graph Diagnostics: invalid connections, missing inputs and unsupported combinations are identified in the graph, with navigation to the affected nodes and complete settings in the Inspector.
  • Cloth: added mesh-based fabric simulation with mapped pins, stretch, shear and bending, animated Attach constraints, Stitch and progressive Sew seams, Balloon pressure, Plasticity and Tearing.
  • Soft Body: added deformable volume simulation for closed meshes, with Volume Stiffness, Shape Stiffness, material maps, Plasticity and contacts with particles and other deformable objects.
  • Strands: added Curve-based hair guides, ropes, cables and strings, with material presets, pinning and animated attachments, stretch, bend, twist, breakage, spatial maps and optional self-collision.
  • Deformable resolution: simulate reduced geometry or a custom proxy while retaining the detailed visible shape for preview and export. Added Multigrid options for stiff Cloth and Soft Body setups; Cloth Tearing and Soft Body Plasticity require their Local XPBD modes.
  • Deformable material data: map material and contact properties with vertex groups or Fields, and inspect Strain, Stress and Damage through simulation attributes and GPU Preview heatmaps.
  • Deformable/Pyro interaction: Cloth and Soft Body can block and move live smoke while gas pressure pushes back on them. Added Pyro-driven Strand motion, heat damage and softening, and continuous Smoke, Fuel and Color emission from moving deformable surfaces.
  • Dynamic Collider: added simulation-driven rigid meshes that move and rotate through contacts with particles, deformables and other colliders. Liquid pressure can lift and turn submerged bodies, and optional Pyro Interaction lets live gas move them.
  • Physics Events: react to particle birth, death, collisions, fluid impacts, tears and deformable thresholds by spawning particles or emitting Pyro. Nodes add event filtering, accumulation, cooldowns, rate limits and delays, plus actions to modify source data, change groups or break constraints.
  • MPM materials: added a stretchable Rubber material, per-material Data Mapping in Lists and Nodes, mask-driven Material Changes and Domain Friction. Improved material volume preservation and response under compression.
  • MPM Pin Groups: attach named particle groups to animated objects, with adjustable Pin Strength. Volume emitter Group Regions assign different parts of one fill to separate groups for stretching and anchored-material setups.
  • Granular and Particle Sleep: added Bonded Clumps for pieces that hold together and crumble when their bonds break. Optional Particle Sleep in Granular and MPM holds settled particles and wakes them through motion or masks.
  • Shape emitters: added Rectangle, Disc, Point, Box, Sphere, Cylinder, Cone and Torus sources without requiring source objects. Edit dimensions and transforms directly in the viewport with gizmos, G/R/S, snapping and Auto Keying. New systems start with a ready-to-emit Rectangle.
  • Emission controls: added Source Speed birth masks and Radius Scaled mass for particles whose birth mass should follow their size. Improved jittered volume fills and complete Grid/Hexagonal filling at source boundaries.
  • Volume Bind: hold particles inside an animated mesh using Exact or Spring behavior, then release them progressively with Masks, Data Mapping or particle attributes. Animated polygons can change their triangulation while particles retain their binding. Released particles can inherit the mesh motion for crumbling and disintegration effects.
  • Target: added mesh-surface, vertex, curve and volume targets, stable Random or Nearest assignment, approach and arrival controls, ordered Target Sequences and mapped Release.
  • Collider Weight Maps: use painted vertex groups or float attributes to vary Bounciness, Friction, Adhesion and Stickiness across Collision and Dynamic Collider surfaces. Improved continuing surface contact for PBF and SPH liquids.
  • Mesher Collider Contact: optionally close small gaps between reconstructed particle surfaces and colliders, including sloped surfaces. This adjusts the generated mesh without changing particle motion.
  • Masks: added independent Data Mapping stacks for masks and reusable composed mask expressions in Nodes, allowing the same mask to be combined and reused across compatible controls.
  • Setup Presets: added a global library for Particles, Pyro, combined Collections and Terrain graphs, with JSON import/export and scene-reference assignment. Terrain presets include editable ramps and curves; Use Saved Dimensions optionally applies Terrain Size and Height Scale to all terrains in the scene.
  • Curve Presets: added factory shapes and user curves with visual previews, search and JSON import/export for remapping, lifetime, easing, falloff and Trails profile editors in Lists and Nodes.
  • Initial States: capture an entire simulation, Group, Emitter or Dynamic Collider and combine compatible captures from different frames as the starting state. Coupled Pyro state can be included where required.
  • Particle Inspector: inspect live particle values, track individual particles, compare Data Mapping inputs and results, and display sampled values in the viewport without changing particle colors.
  • Particle Info: added Shader Editor and Geometry Nodes access to particle age, lifetime, velocity, mass, group, emitter, stable random and user data. Enable the required attributes on the post effect before simulating or baking.
  • Output and caching: extended Output Cache and Alembic to Cloth, Soft Body, Strands and Dynamic Colliders, and expanded in-memory caching across geometry outputs. Reduced-resolution deformables export their detailed visible shape.
  • Point Cloud loops: added Make Loop with adjustable Blend Frames and Loop Check warnings. The beginning and end need similar particle distributions and motion for a convincing transition.
  • Pro Terrain: added a separate terrain node editor for procedural landscapes, geological forms, hydraulic and thermal erosion, weathering, drainage, rivers, sediment, masks and surface coloring.
  • Terrain drawing: draw and edit roads, guided rivers, islands, ridges, valleys, plateaus, lake basins and brush masks using editable Blender curves.
  • Terrain preview and export: inspect 1K, 2K and 4K terrain with editable color ramps, color-map presets, sunlight, soft shadows and atmospheric lighting. Added Auto Update, Preview Cache, progress and cancellation, plus exports up to 16K for heightfields, meshes, base color, normal maps and packed texture channels.
  • Volume Advection: renamed VDB Advection to Volume Advection to reflect its support for external VDB volumes and live Pro Pyro fields.
  • Performance and stability: reduced GPU memory use for fluid and Pyro simulations and improved playback responsiveness in Nodes. Refined FLIP volume preservation, thin-film surface tension, sheeting and whitewater, and corrected combined Particle/Pyro preview refreshes during playback and timeline catch-up.
  • Documentation: added a dedicated documentation site with 15 beginner tutorials, expanded control references and practical case studies for particles, fluids, deformables, Pyro and terrain.

v5.3.5 (2026-10-12)

GPU Preview reliability and support diagnostics

  • Fixed GPU Preview not appearing on affected Windows Vulkan setups, including when enabling or re-enabling the add-on after Blender has started.
  • Improved graphics card checks and made automatic card selection consistent on computers with multiple equally suitable GPUs.
  • GPU Preview now automatically retries after temporary connection problems, helping particles, trails, and meshes appear without restarting Blender.
  • Simulation errors now stop playback without repeated error popups. After correcting the problem, use Retry Solver to continue.
  • Added Export Diagnostics and optional Start Detailed Logging in the add-on Preferences to help support investigate simulation and preview problems.

Pro Pyro Windows cache paths and AMD solver stability

  • Fixed VDB baking to Windows folders and filenames containing accented or other Unicode characters.
  • Fixed baking to long Windows cache paths in Blender 5.2 and newer. Earlier supported Blender versions show a clear error when a path is too long.
  • Fixed solver startup and particle simulation failures on affected AMD GPUs.
  • GPU startup failures on Windows now show troubleshooting guidance directly in the add-on.

v5.3.3 (2026-09-30)

  • Baking Finished now appears only after every VDB file has been saved successfully.
  • Cache folders are checked for write access before baking or saving an initial state, with clearer feedback for invalid or unwritable locations.

v5.3.2 (2026-09-16)

Trail playback stability update

  • Improved Trails stability on Windows so history-based trails stay continuous and visually steady during normal playback.
  • Scenes that need more time to simulate now keep their trail motion consistent instead of showing flicker or gaps when Blender cannot keep up in real time.
  • Manual timeline jumps now rebuild trail history reliably, so you can move to another frame and continue working without broken trails or unexpected crashes.
  • GPU Preview and Blender Geometry now follow the same continuous trail-history workflow during playback and timeline navigation.

v5.3.1 (2026-09-09)

Timeline workflow bug fix

  • Fixed Catch Up Timeline Jumps in Pro Pyro so the OFF state is respected consistently during live preview, historical jumps, loaded-scene initialization, and coupled Pro Particles/Pyro workflows.
  • Added a separate Catch Up Timeline Jumps toggle to Pro Particles. Disable it to jump across long timelines without replaying every skipped simulation frame.
  • In coupled Pro Particles and Pro Pyro setups, skipped frames are replayed only when catch-up is enabled on both systems.

v5.3.0 (2026-09-03)

  • Surface Attach: expanded attachment probability/range/tolerance/outside-only options, distance-based Custom Distance variation, mesh or surface-bearing curve targets, Friction, inherited surface motion/speed/rotation, holding behavior, and release controls.
  • Automatic geometry motion: relevant emitters, colliders, and geometry-based effects now track static, transformed, and deforming geometry automatically; obsolete manual geometry-motion switches were removed from current authoring.
  • Particle Blend: expanded the former color-only blend into neighborhood blending for Radius, Scale, Mass, Rotation, and Color with blend Mode, Distance, Strength, and optional Max Age/Units. Strength and attribute blend amounts can be entered above the normal 0-1 slider range, up to 10.
  • PBF Fluid: improved emitter-momentum preservation and fluid stability/terminology, added source-based Fluid Mixer controls, and moved surface reconstruction out of the solver effect into the standalone Mesher.
  • VDB Advection: can now use either a VDB Volume or live Pro Pyro source, select exact external grid names/field sets, and persist Smoke, Temperature, Fuel, Flame, and Color onto particles with per-channel Influence, Set/Add operations, outside-domain behavior, sampling, and falloff.
  • Post Effects rebuilt: the main Pro Particles tabs are now Emitters, Effects, Post, Outputs, and Groups. The current Post stack is Point Cloud, Trails, Instance, Mesher, Upres, and Dendrite. Point Cloud, Trails, Instance, Mesher, and Dendrite support the native GPU Preview/Blender Geometry workflow; Tracer, Plexus, the standalone Materials tab, and Geometry-Nodes-generated post workflows were retired from the current UI.
  • Point Cloud: added native GPU viewport shapes, fixed/particle sizing, particle/custom color, filters, Blender Geometry target/material, and selectable geometry-attribute profiles.
  • Trails: added native GPU trail playback and Line/Tube output; Particle Trails, sequence, nearest, cluster, and Constraint Links linking; destination-group filters; trail length/freeze behavior; thickness/profile/fade/rounding; spline/intermediate-point controls; color/particle-color sampling; and selectable geometry attributes.
  • Instance: added layered object/collection sources, source weighting, scale/color/rotation sourcing and variation, shading/material controls, animated-source freezing, object alignment, billboard/camera modes, native GPU preview, and particle geometry-attribute profiles.
  • Mesher: added standalone GPU surface reconstruction with Spheres/Zhu-Bridson/Anisotropic modes, Triangles/Quads, particle radius controls, particle/fluid and Pyro Volume layers, smoothing layers, Color/Velocity export attributes and blur, bounds/open-side/clipping controls, small-part cleanup, and Water Level correction.
  • Upres: added persistent render-only reconstruction/detail particles with Group/Emitter filtering, child/strength/count/spread controls, interpolation/reconstruction/surface/flow/density controls, distribution relaxation, attribute variation, destination Emitter/Group options, and user-data inheritance.
  • Output workflow: added a dedicated Output tab. Output Cache can bake multiple selected Point Cloud, Trails, Instance, Mesher, and Dendrite streams for playback without recalculating the simulation, with folder/version/range/source controls and support for either live display mode. Alembic can export Particles, Point Cloud, Instance, Mesher, Trails, or Dendrite with Z-Up/Y-Up coordinates and selectable attributes.
  • Interactive caching: retained a separate in-memory Geometry playback cache with Use In-Memory Cache, Memory Cache (MB), cached-frame/memory display, while persistent final output moved to Output Cache.
  • GPU Preview: parameter changes now refresh the current frame automatically, replacing the Live Update toggle. Added switching to Blender Geometry without repeating the current simulation frame, preview support for Trails, Instance, Mesher, Point Cloud and Dendrite, and Show GPU HUD controls for position, scale and opacity. Improved guidance when GPU Preview is unavailable. The Vulkan viewport is no longer labeled Beta.
  • Multiple Blender scenes: multiple scenes can contain Pro Particles or Pro Pyro setups, while one configured scene simulates at a time. Switching the active simulation scene resets the live simulation state and in-memory caches; persistent Output Cache/VDB data remains the workflow for preserving completed results across scene switches.
  • Parameter behavior: procedural Scale now consistently means larger spatial features at higher values in Advanced Color Noise, Masks, Turbulence/Curl Noise, and Flow Field procedural layers. Advanced Color Direction/Adjust behavior and Mask Noise Contrast were clarified, Flow Field ABC exposes Scale instead of Frequency, and Change Direction Blend Falloff now supports 0 for full response.
  • Evaluation preview: native particle GPU Preview now has no frame or particle limit in evaluation builds. Points/cache output remains limited to 120 frames and 25,000 particles; Output Cache baking and Alembic export remain unavailable. Pro Pyro Fast GPU Volume has no evaluation frame limit, while VDB preview remains limited to 120 frames and VDB baking remains unavailable.
  • Pro Pyro defaults: Add-on Preferences were simplified to Runtime & GPU plus Pro Pyro Defaults. New Pyro setups default to Dense and to native GPU Preview where supported; Color Channel, Fire Channels, and Default Max Sparse Cells remain configurable.
  • Pro Pyro Dense boundaries: added per-face dense-domain boundary profiles and Setup presets including Open Domain, Wind Tunnel, Slip Box, and Solid Box, with Open/Inflow/Slip Wall/Solid Wall behavior and inflow content controls.
  • Pro Pyro Data Mapping: added layered mappings for Physics, supported Effects, and Emitters with Pyro-field, velocity, spatial, procedural, time, vertex-weight, Geometry Nodes color, and particle-color sources.
  • Particle/Pyro exchange: particle Smoke, Temperature, Fuel and Flame values can be used with live Pro Pyro data in Logic, Data Mapping, effects, geometry attributes, caches and exports.
  • Pro Pyro cache/output: Cache now exposes selectable export channels, Preview History Frames, versioned VDB baking/playback, and cache range controls. Pyro mesh creation is now handled through the standalone Mesher Pyro Volume layer and Alembic through the central Output workflow.
  • Performance and stability: improved simulation startup, particle emission continuity, GPU Preview updates, timeline catch-up and memory use.
  • ⚠️ Breaking change - Post Effects: Post Effects were rebuilt for 5.3.0. Existing Post Effect setups from 5.2.x and earlier are not compatible with the new Post stack and must be recreated after upgrading.

  • ⚠️ Simulation speed is now tied to the project's framerate. For the old behavior, set your framerate to 60fps. Please also check the new Motion Mode settings (static/rigid/deforming) on your emitters and effects.
