Folder structure

Package and folder structure of realvirtual

Starting with version 6.3, realvirtual is distributed as UPM (Unity Package Manager) packages. The folder structure changed significantly from the previous Assets/realvirtual/ layout used in 6.0 and earlier.

Package Overview

realvirtual UPM package structure

realvirtual is split into two UPM packages:

Package	Location	Description
io.realvirtual.starter	Packages/io.realvirtual.starter/	Core framework — drives, sensors, signals, transport, gripping, logic
io.realvirtual.professional	Packages/io.realvirtual.professional/	Professional add-on — IK, CADLink, interfaces, multiplayer, and more

UPM packages are read-only in Unity. You cannot edit files inside Packages/. Place your own scenes, scripts, and assets in the Assets/ folder.

Starter Package Layout

The Starter package (Packages/io.realvirtual.starter/) contains:

Folder	Description
Assets/	User-facing assets you drag into scenes
Assets/3DPrefabs/	Industrial 3D models (conveyors, robots, boxes, fences)
Assets/Materials/	Industrial materials (plastics, metals, lamp indicators)
Assets/Prefabs/	Core functional prefabs (realvirtual.prefab, signal prefabs, interfaces)
Assets/UIPrefabs/	Runtime UI overlay prefabs
Assets/Settings/	Editor gizmo options, camera presets
Assets/RenderPipelines/	URP pipeline configuration and settings
Runtime/	All runtime C# scripts (components, behaviors, interfaces)
Editor/	Editor tools, inspectors, and toolbar
Samples~/	Demo scenes — import via Demo Scenes Browser or Package Manager

Professional Package Layout

The Professional package (Packages/io.realvirtual.professional/) contains:

Folder	Description
Runtime/	Pro features organized by domain
Runtime/IK/	Robot Inverse Kinematics + robot prefabs
Runtime/Interfaces/	All Pro interfaces (OPC-UA, TwinCAT, KUKA, UR, Modbus, etc.)
Runtime/CADLink/	CAD file import
Runtime/PathTracer/	Motion trail visualization
Runtime/Statistics/	Simulation statistics
Runtime/Multiplayer/	Multi-user networking
Runtime/HighlightSystem/	Object highlighting and selection
Runtime/DistanceSystem/	Distance measurement and connectable objects
Editor/	Pro editor tools
Samples~/	Pro demo scenes (PLC Interfaces, Robotics, Robot Interfaces, Advanced Features)

Key Asset Locations

When setting up scenes, you will frequently need these assets:

What you need	Where to find it
Main framework prefab	Packages/io.realvirtual.starter/Assets/Prefabs/realvirtual.prefab
Industrial 3D prefabs	Packages/io.realvirtual.starter/Assets/3DPrefabs/
Materials library	Packages/io.realvirtual.starter/Assets/Materials/
PLC signal prefabs	Packages/io.realvirtual.starter/Assets/Prefabs/
Interface prefabs (Pro)	Packages/io.realvirtual.professional/Runtime/Interfaces/<Name>/
Robot prefabs (Pro)	Packages/io.realvirtual.professional/Runtime/IK/
Demo scenes	Import via Demo Scenes Browser or Window > Package Manager > Samples

Your Project Content

Place all your project files in Assets/:

• Scenes — your simulation scenes

• Scripts — custom C# scripts and behaviors

• Prefabs — your own reusable prefabs

• Materials — custom materials

• Imported CAD data — files imported via CADLink

Previous Folder Structure (6.0 and earlier)

In versions before 6.3, realvirtual was distributed as a .unitypackage installed into Assets/realvirtual/. This folder no longer exists in UPM-based installations. See the Upgrade Guide for migration instructions.
