Release Notes

New features, improvements and fixes of realvirtual WEB and realvirtual CONNECT, newest release first. Each entry names the product and version it belongs to.

realvirtual WEB 6.4.3 · 2026-10-15

Fixed

• Customer source deliveries no longer stop at their own secret check.

realvirtual WEB 6.4.2 · 2026-10-15

Improved

• The robot loading screen appears only while the viewer starts; switching scenes stays in the HMI.
• Ambient occlusion on Max Quality is sharp, and the Fast preset renders without it.
• WebGPU rendering is complete: no more grey screen, and picking works.

Fixed

• A part held by a gripper no longer lets the parts behind it drive into it on a conveyor.
• The Problems window remembers when you closed it for a model.
• Gizmos draw underneath the HMI panels.

realvirtual WEB 6.4.1 · 2026-10-13

Improved

• A new loading screen shows a robot cell whose cycle follows the real loading progress.
• PLC programs show a read-only preview of their Structured Text in the Property Inspector; a click opens the program in the PLC editor.

Fixed

• The viewer starts with the proven startup sequence of 6.3 again; the faster startup that shipped with 6.4.0 is withdrawn.

realvirtual WEB 6.4.0 · 2026-10-12

New

• Virtual PLC (commercial): several Structured Text programs per scene, LogicStep sequences convert to ST and can be taken over by a program, an online view with live values and active branches, and the RV_SimulationMode system variable.
• Laser Welding Assembly Station demo, controlled entirely by the virtual PLC.
• Record video (commercial): raster download, still images, path-traced cinematic frames with look presets and motion blur, optionally with the HMI in the recording; deterministic frame-by-frame recording from the command line and over MCP.
• Render modes Unlit / Shaded / Toon (Wireframe in the editor), Max-Quality and Fast presets, and a frame rate limit (Off / 30 / 60).
• WebLabel: text in the 3D scene with hover, select and pin; WebError marks in the overlay.
• WebOperatorPanel: an operator panel stored as JSON in the GLB, with a JSON editor.
• Signals: a “Used by” cross-reference list, signal inspector and PLC binding checked against the gateway’s address rules, a model/gateway reconcile report, model signals created from a CONNECT interface, and safe signal rename across model, CONNECT and ST code.
• PLC auto-map from model signals to S7 / PLCSIM interface signals with a match report.
• CONNECT edit forms for eleven more interface types, B&R PVI included.
• Hierarchy filter by component category.
• AASX files linked from the project folder.
• Encrypted share links for GLB files, and hosted project links with a password gate and encrypted models.
• AGVs: selectable vehicles with DES statistics and distance control (moving block).
• Commissioning: move and remove workpiece carriers; loads seat in and are placed on carriers.
• Quick Edit: Physics and BoxCollider authoring, and a Groups section under Kinematics with hover preview, eye/isolate, rename, dissolve and Add Group (also as MCP tools).
• Editor: wireframe view, lossless GLB weld on import, one-step mesh separate, selection stats.
• Drive_Cylinder valve modes (single- and double-acting).
• H hides and shows the HMI overlay.
• Third-party license notices in every WEB and CONNECT build.

Improved

• The view controls at the bottom right are one compact strip.
• STEP imports convert on CONNECT by default, with full assembly colours.
• PLC inputs start with the model’s value instead of the type default.
• Writing to a live PLC asks for permission first and shows when no data arrives.
• Hosted pages connect to a local CONNECT and name the cause when that fails.
• Quick Edit: Add Kinematic and Add Group only set the Auto Assign target; the toggle alone switches the mode on (Escape turns it off).
• Simulation and commissioning share one engine contract: cylinder feedback on start, NC emergency stop, edge waits and a defined I/O state after reset.

Fixed

• The HMI no longer crashes on a mode switch, and sensor beams no longer multiply.
• Viewer writes reach signals that CONNECT adds while connected.
• F framing ignores hidden parts.
• AGVs hide the path line they drive over; the scanner field no longer counts as vehicle body.
• DES animations repaint without user input.
• Hosted deploys never publish CAD source files.
• A document draft never shadows a newer document file.
• Open dropdown menus stack above the HMI tiles.

realvirtual CONNECT 1.5.0 · 2026-10-12

New

• Signals can be renamed atomically in the gateway: the store, the interface configuration and the viewer stay in step, and the realvirtual WEB rename dialog uses it.
• The signal schema reports an address rule per container and the MQTT topic mode, so the viewer checks PLC addresses against what the interface really accepts.

realvirtual CONNECT 1.4.0 · 2026-10-07

New

• AI Bridge from the hosted realvirtual WEB. A realvirtual WEB page that CONNECT did not serve — the demo on web.realvirtual.io or your own https site — can now connect its AI Bridge to the CONNECT on your computer. The first time, CONNECT asks in a tray window whether that page may control the 3D viewer for your AI assistant; one click on Allow and it connects, without editing any configuration and without a restart. Deny is remembered as well. Both lists are under Details ▸ MCP server ▸ AI Bridge origins, where an entry can be removed again — removing a permission disconnects that page at once. Running PLC and MQTT connections are not interrupted. CONNECT without a tray (Linux, ctrlX) does not ask; there the page address still goes into AllowedOrigins. Bridge:PairingEnabled: false switches the feature off.
• Robot interfaces: KUKA, Universal Robots, igus, RoboDK and Wandelbots NOVA. Six new interface types bring robot simulations and controllers into CONNECT without Unity in the loop: Kuka (KUKA OfficeLite through the Y200 TCP server: $IN/$OUT bits and joints), KukaRsi (KUKA iiQKA VRC or controller over RSI Ethernet, every packet answered at once with the IPOC echoed), UniversalRobots (RTDE: joints, digital outputs and robot state; digital inputs via URScript), IgusRebel (igus robot control via CRI: joints, outputs, global signals, joint and cartesian moves), RoboDk (joints, station parameters, program start / stop / loop of a running RoboDK station) and WandelbotsNova (joints, controller IOs, Wandelscript start / stop / loop). Joint positions appear as <id>.axis1… automatically. Moves and program starts react to a rising edge only, so a trigger that stays true across a reconnect starts exactly one move, never a second one; feedback comes back as busy / done / error. CONNECT never starts RoboDK by itself.
• Controller and generic interfaces: Mitsubishi, UDP, WebSocket Realtime and WINMOD. Mitsubishi reads and writes bit and word devices of a MELSEC PLC over MC protocol 3E with optimized batch reads and GX Works3 CSV import. Udp exchanges fixed binary telegrams with a PLC, SCADA system or your own tool (<offset>:<BOOL|INT|REAL>, byte order selectable, CSV symbol table). WebSocketRealtime speaks the realvirtual WebSocket protocol v2 as server or client — to Unity, another CONNECT or the ctrlX bridge; the server listens on loopback by default and needs an API key before it accepts other machines, browser origins must be listed. WinmodY200 couples to WINMOD through its Y200 shared memory (Windows only), with WINMOD signal list import.
• All ten new interfaces write to the controller only while Allow web to PLC is on; values blocked while it was off are not replayed when it is switched on.
• The new interfaces in the realvirtual WEB editor. The CONNECT panel has an edit form for each of the ten new types and for the new settings listed under Improved. WINMOD is offered only when the connected gateway supports it. Passwords, tokens and API keys stay hidden; leaving such a field empty keeps the stored value.
• B&R controllers through PVI. The new interface type Pvi connects B&R controllers and ArSim over ANSL (or INA2000 for older CPUs) and reads and writes variables by name — global, task-local and module variables, structure members and array elements (gCounter, Prog1:localCnt, stData.Speed, arr[3]). Nothing has to be released in the PLC project. Browse lists the tasks and variables with their types and expands structures and arrays into single signals. Every interface reports the CPU state as <id>.cpu.state and <id>.cpu.running. Writes go to exactly the addressed member, never to a whole structure, and only while Allow web to PLC is on. Windows only; CONNECT uses the B&R PVI installation of the PC and never ships the B&R files — without a PVI runtime licence, PVI disconnects after its 2-hour trial (B&R industrial PCs need no licence). The realvirtual WEB editor has a form for the new type.

Improved

• Denso: P<n> position variables can be read and written as x/y/z/rx/ry/rz (mm / degrees) plus the figure, and axis<N> binds a joint under your own signal name.
• Siemens S7: TIA .sdf symbol tables can be imported for signal discovery, and the connection timeout is configurable.
• Festo: certificate validation can be switched off for test setups, and the connection timeout is configurable.
• ctrlX (tunnel): the publish interval of the bridge can be set per interface.
• Keba: the input topic name and the connection timeout are configurable.
• WINMOD: an optional keep-alive watchdog reports an error and reattaches when WINMOD stops updating its cycle counter.
• FMU: String variables are exchanged as text signals; Enumeration variables work end to end.
• PLCSIM Advanced (native): RemoteAddress connects to a PLCSIM Advanced instance on another PC.
• Configurable timeouts for Modbus, S7, Festo and Keba; the EtherNet/IP timeout applies to every tag.
• Stricter signal-name check: a manual signal named like another interface’s automatic signal (for example robot1.axis1) is now rejected when the interface is saved, instead of two interfaces writing the same signal.
• Text signals from Browse stay text. A discovered String / Text / WSTRING variable is now bound as a text signal in the realvirtual WEB CONNECT panel instead of a number, for every interface type.
• Third-party licence notices: every CONNECT build ships a complete list of the open-source components it contains and their licences.
• PLC inputs start with the value from the model. A signal that CONNECT creates while a viewer is connected (new interface, PLC auto-map → Apply) is no longer written to the PLC with a default false; the viewer supplies the model value (for example E-stop released, control on, automatic mode), and the first real value wins.
• Signals added while the viewer stays connected are picked up automatically, so values set in the viewer reach the PLC without reloading the page.
• When the viewer writes to an interface whose Allow web to PLC is off, CONNECT now counts the blocked writes, names the affected signals and reports a per-interface read health in the status — and the gate can be switched from the viewer in one click.
• AI assistants: several viewer tabs can stay connected; the visible or claimed tab receives the commands, the others wait in standby instead of being disconnected.

Fixed

• GET /config no longer returns credentials of profile snapshots in plain text. Passwords, tokens and API keys were redacted for the interfaces but not inside profiles[]; both are redacted now.
• Modbus client: the connection timeout now also bounds every read and write, so an unresponsive device can no longer hold the interface indefinitely.
• Keba: a login that times out is now shown as an error and retried with the normal reconnect delay, instead of being retried silently.
• Modbus server answers at once and on every unit id. A PLC acting as Modbus master against CONNECT waited for the next worker tick on every request — about 30 ms per request on Windows, so a PLC task of 5 ms ran at roughly 66 ms. Requests are now answered on arrival (median about 0.2 ms), and a master’s writes reach the signals just as fast. The server also answered unit id 0 only; a master with the usual slave id 1, the recommended 255 or any other id got no answer and looked like a dead device. Every unit id is now served with the same process image.
• Modbus relay: responses are matched to their requests by transaction id, and only one request per device is in flight.

realvirtual CONNECT 1.3.1 · 2026-10-01

New

• Separate folder for FMUs. The new setting Fmu:StorePath keeps FMU packages and their binaries in a folder of your choice, e.g. one your company’s application-control policy (AppLocker, WDAC) allows, without moving the rest of CONNECT’s data. Also as environment variable Fmu__StorePath or --Fmu:StorePath.

Improved

• Confirming an FMU from the public realvirtual WEB at web.realvirtual.io now works without configuration.
• When an FMU cannot be loaded, CONNECT names the cause: blocked by a company policy, a missing dependency, or a non-64-bit binary.
• A refused FMU confirmation names the page address and the AllowedOrigins setting that admits it.

realvirtual WEB 6.3.47 · 2026-09-30

New

• Zone component: Detect, Block and Hold zones with activation, gizmo and editor handles.
• Layout planner: every placement gets a sibling-unique name.
• Quick Edit: filter, foldout tree and resizable list for the kinematics section.
• Pre-placed MUs and collider-based passive loads; MUs are authorable in the asset editor.
• web_component_schema MCP tool with spec-backed authoring rules.
• The camera follows the AI agent’s edits while the user is idle.
• Navigation: scale-adaptive wheel zoom, orbit and pan about the point under the cursor, touch gestures, zoom-to-cursor as an option; embed viewer navigation parity.
• The CONNECT panel explains what CONNECT is for whenever no gateway is connected.

Fixed

• Transport ignores belts on another level for surface pick and accumulation.
• A belt driven backward with DriveTo transports backward.
• Navigation feel restored after the scale fixes.

realvirtual WEB 6.3.46 · 2026-09-28

Fixed

• Customer deliveries build project plugins that use the viewer core.

realvirtual WEB 6.3.45 · 2026-09-28

New

• FMU co-simulation: attach an FMI 2.0 FMU to a node, run it through CONNECT after a trust confirmation, edit parameters and start values, restart it from a signal. Includes a bouncing-ball FMU demo.
• Signal units: signals carry units and bindings convert between them.
• Mechanisms: cartesian paths, a trajectory visualizer (path line, playback marker, waypoints) and offline drive sizing with trajectory, inertia override and SERVOsoft export.
• Projects dashboard: search the documents of all projects, quick-open type-ahead, “Open in new tab”.
• Documents remember and restore their last-used mode.
• Seven more drive behaviours; every drive behaviour can be added in the editor.
• Mesh section in the property inspector with baked-geometry details.
• Nested references: referenced assets may contain references of their own.
• Delta robot kinematics model in the demo project; descriptions for all demo and library models.
• Build time shown in the version line.

Improved

• Property inspector: one value column, a ⋮ menu for component actions (Replace, Remove), Jog − | Stop | Jog + as one control, collapsible package details, English texts throughout.
• Number fields accept comma or dot as decimal separator.
• Buttons, menus, shortcuts and AI tools share one command system with consistent enabled state and reasons.
• Faster, more precise picking and hover on large models; groups no longer cost draw calls and can still be hidden and isolated.
• Asset cache verifies file versions and never keeps a missing file.
• Better performance for large layouts with many parts.

Fixed

• Typing “9,81” in a number field no longer stores 9.
• FMU section header follows the FMU state.
• Viewer mode shows Play, Pause, Reset and speed again.
• Paths honour the global speed override.
• Follow-position drives keep rendering while they move.
• Snap picker opens only on a click near a marker, not on a drag.
• Reset restarts logic steps.
• Picking imported CAD in the editor works again.
• A failed model preparation is shown as a load error.
• Project thumbnails refresh when a document changes.

realvirtual CONNECT 1.3.0 · 2026-09-28

New

• Siemens PLCSIM Advanced, natively. A new interface type PlcSimAdvanced talks to a running PLCSIM Advanced instance through the official Siemens simulation API in-process — no coupler process, no shared memory, no PUT/GET. It attaches to a registered instance by name, browses its tags symbolically, exchanges them as one batch read plus one batch write per cycle, and rebuilds itself after a TIA software download. Unlike the existing S7comm route to the same instance it needs no absolute DB addresses, no non-optimized blocks and no virtual Ethernet adapter — Softbus works. Windows only; the Siemens API is never shipped with CONNECT, it is loaded from the customer’s own PLCSIM Advanced installation. Without that installation the interface is parked with a readable reason in GET /status instead of retrying forever. See doc-connect-interfaces.md § PLCSIM Advanced worker (native API).
• FMU co-simulation. CONNECT runs FMI 2.0 co-simulation FMUs that realvirtual WEB uploads, in a separate worker process: a trust confirmation per package, a lease per connected viewer, start-value overrides, restart in place, and simulation time that follows wall-clock time with a bounded catch-up.

Fixed

• OPC-UA client timeout is applied in seconds as configured; it was read as milliseconds.
• The update check verifies the signature of a downloaded update reliably.
• The startup port check no longer reports a wrong location for an already running gateway.
• An FMU package can be uploaded again after it was deleted while in use.
• PLCSIM Advanced: a large project no longer fails to browse. The worker asked the instance for every data block on every connect; PLCSIM Advanced caps its tag list at 500 000 entries (array and struct elements included), so a large safety project answered -43 NotEnoughMemory and the interface never came up. Without a Data Block Filter CONNECT now requests the process image and the markers only, plus exactly the data blocks the configured signal addresses name ("Block".Member); a browse lists data block tags only for the blocks named in the filter. If the list still overruns the limit, CONNECT retries that browse once with HMI-visible tags only and reports it as tagListFallback in GET /status (next to tagListDetails and the dataBlockFilter actually used) — the configured setting is never overwritten. Tag counts per area and per requested data block are logged, including a warning for a block that returns nothing. See doc-connect-interfaces.md § Behaviour worth knowing.

realvirtual WEB 6.3.44 · 2026-09-17

Improved

• bake() is the only render and pick pipeline: BatchedMesh arenas, face-range pick tables and proxy highlights are gone
• One placement primitive in the viewer core; planner placements are BakedAsset instances with chunk picking and chunk-outline highlight
• Scene-ready contract: placements-materialized event and whenSceneReady(), reopened layouts re-instantiate their placed references
• Per-pass frame stats, shared sensor visualisation geometry
• Faster and automatic /dev deploys (build cache, parallel upload, watcher)
• Projects: Add and Locate open the folder instead of suppressing themselves

realvirtual WEB 6.3.43 · 2026-09-15

Improved

• TransportStopper collider and LogicStep WaitForStopped, wired through the LogicStep builder
• Recents as a pinnable flyout off the Projects folder
• Agent eye narrowed to three channels, its monitor panel reworked into a shared activity row, with the captured images in an HMI filmstrip
• Editor export fixes: driven nodes export from their home pose, and source template materials plus glTF provenance survive an in-place test export
• Energy chain survives sparse CAD tessellation
• Test suite green end to end: node 1547, browser 14623, 0 failures

realvirtual CONNECT 1.2.4 · 2026-09-13

New

• A delivered workspace gets a Start-menu entry for THAT workspace. A gateway started with --project-root no longer offers the portable install (copy into the profile, link without a project root), which produced a project-less gateway drifting from the workspace’s pinned CONNECT version. The shortcut now points at tools/connect/realvirtual-Connect.exe with --project-root "<workspace>", is named after the workspace folder inside the single realvirtual group, and the machine-install upgrade question is not asked at all.
• web_eye returns all its channels. A multi-channel capture (beauty, idmask, depth, normals, edges from one camera pose) is forwarded as one image block per channel, in declared order, so the sidecar’s pixel coordinates apply to every channel of the same result.

Improved

• The SEW MOVI-C catalog preset is described as a signal interface, not a drive interface.

Fixed

• OPC UA client: missing System.IO using.

realvirtual CONNECT 1.2.3 · 2026-09-07

New

• SEW MOVI-C interface (MQTT Json topic mode). One flat JSON object per topic carries the whole process image; the signal name is the JSON key, no addresses. Matches what a SEW MOVI-C / Codesys station publishes and the SEWSimInterface of realvirtual for Unity, so an existing SEW simulation moves to the browser unchanged. Receive topic (PLC outputs) and publish topic (PLC inputs, cyclic, default 100 ms) are created together from a SEW symbol table import. See doc-connect.md § MQTT Json topic mode (SEW).

Fixed

• Config updates keep omitted credentials and their provenance instead of dropping them.
• Float signal values no longer overflow on the MQTT/WebSocket boundary.
• stage-public follows the project folder model; -Public bundles no demo content.

realvirtual WEB 6.3.36 · 2026-09-03

No release notes were recorded for this version.

realvirtual WEB 6.3.34 · 2026-09-01

New

• Chain component: the Unity Chain is now available in the web runtime — chain links follow a spline path and are moved by a Drive, with GLB round-trip verified against real Unity exports (including a vertical-flip parity fix in glTF space).
• Project manifests: every project now ships a real project.json; the glob-based and synthetic manifest fallbacks are removed, and the former “published:” identity space is folded into the manifest’s documents[] list. Old ?scene= links hop to the right workspace document.

Improved

• README: new “Community Edition vs. Commercial” section, and the public demo’s free-tier evaluation limits are stated explicitly.

Fixed

• GLB fidelity: deduplicated nodes keep their raw glTF name, and loading a model in the authoring editor never mutates the GLB hierarchy anymore.
• Layout Planner: layouts adopted from a GLB now behave exactly like natively planned scenes — the store survives a reload, snap points register, and placements render per object. The planner demo also works on static deployments.
• Embed bundle: React and @mui are kept out of the embed build, shrinking the bundle for iframe/embed use.
• Dashboard: the Libraries tree no longer collapses to zero width.
• Staging: the public demo staging keeps the authored demo manifest instead of overwriting it with a generated delivery manifest.

• Project-local configuration by reference; agents and RAG sources follow the manifest.
• Download-only self-update, one-click remote HMI link for LAN second devices.
• Configurable interface allow-list for trimmed deliveries.

realvirtual WEB 6.3.18 · 2026-08-11

Improved

• Lazy-panel tests: the resource timeline is their only witness, and it is a fixed-size buffer (250 entries by default). This file’s module graph had grown to fill it, so the lazy chunk’s entry — recorded last, at the one moment that mattered — was dropped on arrival. The panels opened and the chunks loaded exactly as specified; the tests then spent their full 15 s budget waiting for evidence the browser had already discarded, and reported it as a timeout. Raised the buffer instead of the timeout: nothing was ever slow.
• Private Node suites: the browser config excludes tests/**/*.node.test.ts but the include glob also reaches into the private sibling, where the same convention went unexcluded — so 11 Node suites were dragged into Chromium and died on the first node:crypto import. They run, and pass, under npm run test:node.
• Regenerated tests/private-dependent-tests.json (+ the tsconfig exclude block): the two FBX tests restored earlier were never added, leaving the community-parity guard red.

realvirtual WEB 6.3.17 · 2026-08-10

Improved

• Autosave data-loss fix (undefined topic in signal mappings) + visible autosave errors
• Inspector bind row for PLC signal nodes (aliased-selection fix)
• Signal chips use full width; hover cards on 3D link badges
• Shiftless chip drag (mouse threshold, touch long-press)
• Drag magnet occlusion check
• Demo scene: machine/robot signals moved onto their machines; 40 signals commented
