FREQUENTLY ASKED QUESTIONS

You need the Unity Editor installed — either a Professional or Standard license. realvirtual.io works as a plugin for Unity projects on Windows, macOS and Linux.

Releases are based on the current Long Term Stable (LTS) release. Within Unity LTS versions, you can always safely update to the latest version.

Usually yes, but only the current LTS release is tested and guaranteed. However, if there is no urgent reason for a higher version, we recommend using the corresponding LTS version.

We recommend a PC with at least 16GB of RAM, 6 or more cores, and a current gaming graphics card.

Only Personal or Professional is required. The Unity Industrial Collection is not needed, as realvirtual.io offers its own CAD interface based on STEP.

Everyone who works with the Unity Editor — i.e., develops digital twins in it — also needs a realvirtual.io license.

You can share the digital twin freely and without license costs — but only as a compiled build, not as an editable project.

Yes, the purchase price is a one-time fee. There is an annual, significantly reduced upgrade package available for existing customers.

Yes, but only on one computer at a time, not on multiple simultaneously.

realvirtual.io uses the extremely powerful Unity Engine as its foundation instead of developing everything from scratch. Direct sales via the internet reduce costs.

Starter is an affordable option for getting started or demos. The Starter version lacks the CAD interface as well as all interfaces beyond Siemens systems.

No, both are included in Professional. These are products for customers who only need individual features.

It provides ready-made parametric simulation components for material flow simulation — ideal for system integrators and material handling technology.

Yes — realvirtual.io Starter is available for free on the Unity Asset Store. It includes a complete demo scene with drives, sensors, transport, and a Siemens S7 interface. Professional comes with a 30-day money-back guarantee.

Directly from realvirtual.io with a quote and bank transfer, or via the Unity Asset Store with a credit card.

Options include: purchase Starter and learn on your own, attend training sessions, or "training on the job" — individual support via Teams.

realvirtual WEB is an open-source, browser-based 3D HMI and machine information system built on Three.js and TypeScript. It connects to real PLCs via WebSocket or MQTT and displays live machine states in 3D — drive positions, sensor readings, alarms, and KPIs. Share a link, and your digital twin runs on any device.

No. realvirtual WEB supports two input paths: export enriched GLB files from realvirtual.io Professional with all metadata and signal bindings, or import any standard GLB/glTF from Blender, SolidWorks, Fusion 360, CATIA, NX and others. Add signal bindings via the open rv_extras schema and custom behavior via TypeScript plugins — no Unity license required.

realvirtual.io Professional is a Unity-based framework for building digital twins — it covers the full engineering workflow: CAD import, behavior simulation, virtual commissioning with real PLCs, and multi-platform deployment. realvirtual WEB is a lightweight browser-based viewer and 3D HMI for delivering digital twins to end users — no installation, no Unity required. They work together: build in Professional, deliver via WEB. Or use WEB standalone with any GLB model.

Dual-licensed: AGPL (free, open source — but any project using it must also be published as open source) or Commercial (€1,920 per developer per year + €200 one-time per delivered machine — proprietary use without open-source obligation).

WebSocket (real-time bidirectional PLC signals), MQTT (IoT and cloud connectivity), Bosch Rexroth ctrlX (direct integration), REST API (polling-based access), SEW SimInterface (via MQTT), Beckhoff TwinCAT HMI (via WebSocket), and Keba (via WebSocket). The realvirtual DataHub serves as a central gateway bridging non-WebSocket-capable industrial protocols to the browser.

Yes. realvirtual WEB is a standard Vite production build — a static file server is sufficient for serving the application. If you need live PLC connectivity or historical data, add the realvirtual DataHub and optionally InfluxDB as a data backend. Deploy on your own infrastructure with full control — no cloud dependency, no login required.

Yes. Via WebXR, realvirtual WEB runs on all AR and XR devices out of the box — Meta Quest, Apple Vision Pro, HTC Vive, Android/iOS AR. No native builds, no app store submissions. One URL works everywhere.

The EU Machinery Regulation (effective January 2027) enables fully digital machine documentation. realvirtual WEB is ready: link PDFs, technical drawings, and spare part lists directly to 3D components and failure messages. Version control via Gitea ensures traceability and 10+ year availability. Technicians open a link, click on a component, and see the relevant documentation in 3D context.
