CMC ViewR

CMC ViewR is an advanced immersive viewing application specifically designed for visualizing CAD data. It supports a variety of immersive experiences, including use with VR glasses and large 3D projections, providing an enhanced and interactive environment for users.

The application supports the import of scenes from realvirtual, allowing seamless integration and visualization of complex industrial digital twin scenes within the CMC ViewR platform.

Restrictions and Limitations

When exporting realvirtual scenes to CMC ViewR, please note the following restrictions:

Unsupported Components

The following components are not supported as CMC ViewR provides its own interaction and navigation systems:

SceneSelectables - Not working (CMC ViewR uses its own selection and interaction system)
DebugConsole - Not working (replaced by CMC ViewR’s debugging and logging features)
RealvirtualRuntimeUI - Not working (replaced by CMC ViewR’s interaction and scene navigation interface)

Custom Scripts Requirement

Custom scripts must be inside an Assembly Definition - Any custom scripts you’ve created need to be organized within an Assembly Definition file (.asmdef) to be properly included in the AssetBundle export. See the Preparing the Scripts section below for detailed instructions.

Overview

CMC ViewR is an XR (extended reality) platform designed specifically for industrial applications, enabling professionals to work with digital twins in the industrial metaverse built directly from 3D data. The platform excels at real-time 3D visualization of CAD data and supports both VR headsets and large 3D projections.

Integrating realvirtual AssetBundles into CMC ViewR

The CMC AssetBundleBuilder enables the visualization of realvirtual Unity scenes in CMC ViewR with full functionality. This guide explains the necessary steps to export a Unity scene as an AssetBundle and load it into CMC ViewR.

Download CMC AssetBundleBuilder

Download and import the CMC AssetBundleBuilder Unity package into your realvirtual project:

📎 CMC AssetBundleBuilder Unity Package

To install:

Download the Unity package file using the download button above
In Unity, go to Assets > Import Package > Custom Package…
Select the downloaded CMC_AssetBundleBuilder.unitypackage
Import all files in the package

1. Preparing the Unity Scene

CMC ViewR uses its own user interface (UI) within the scene. You can keep your Unity cameras and UI elements active - CMC ViewR will handle the viewing environment.

2. Preparing the Scripts

To ensure all scene functionalities are successfully transferred into the AssetBundle, the required scripts need to be placed in a specific directory and associated with an Assembly Definition.

For more information about Unity Assembly Definitions, see the official Unity documentation:

🔗 Unity Assembly Definition Files Documentation

*Unity context menu to create an Assembly Definition*

All realvirtual scripts are already equipped with Assembly Definitions. However, if you have additional functionality, it’s important to include these in a corresponding Assembly Definition. The following figure shows an example.

*Example of an Assembly Definition for additional functionality*

3. Creating the AssetBundle

Once the scene is prepared, the AssetBundle can be built. For this, the CMC AssetBundleBuilder is used. The main function of the AssetBundleBuilder is to convert the objects in the currently loaded scene, along with their scripts, into an AssetBundle, which can then be loaded into CMC ViewR.

To do this, open the AssetBundleBuilder window via the toolbar under the CMC tab. In this window, you need to provide two inputs:

The storage location for the AssetBundle
The name of the AssetBundle

After setting these values, click the Generate AssetBundle button to build the AssetBundle.

4. Importing the AssetBundle into CMC ViewR

In CMC ViewR, Unity AssetBundles with the .unity3d format can be imported. To load an AssetBundle, open the Start tab and select the Import function.

5. Using ViewR

After successfully importing the AssetBundle, the scene can be viewed in CMC ViewR.

Loaded realvirtual AssetBundle in CMC ViewR

CMC ViewR launches with a default desktop configuration. You can rotate the camera using the right mouse button and navigate through the scene with the middle mouse button. More features of ViewR can be explored in the ViewR Manual, which is available at: ViewR Manual.
