DataMesh Director FAQ

DataMesh Studio

1. Can multiple people edit a scenario simultaneously?

No, a scenario can only be edited by one account at a time. Users attempting to open a scenario that is being edited by someone else will not be allowed to do so and will see a prompt saying “Another user is editing the scenario.”

2. Can multiple scenarios be merged or split? Can you switch across scenarios?

No, the current version does not support scenario merging, splitting, or cross-scenario navigation.

3. Can you add a hot zone to image resources?

No, only models and their sub-objects can have hot zones added. For more information on the hot zone, please refer to the Link section in the DataMesh Studio User Manual.

4. Can the camera be deleted or reset?

No, the camera is the default element in the scene. There can only be one camera per scenario, which cannot be added or removed.

The current camera POV (Point of view) cannot be reset but can be adjusted and saved. The “Get Camera POV” function allows you to switch to the camera’s view.

For more information about the camera, refer to the Camera section in the DataMesh Studio User Manual.

5. Why do camera movements not work on MR devices?

Please check the Camera Attribute in the scenario within DataMesh Studio and make sure the “Apply Camera Movement” option is checked. The camera movement feature will only function properly if this option is selected.

6. Is lighting effective in MR mode?

Yes, it is. If you need lighting effects, you need to enable the light sources in the DataMesh Studio scenario. For more details on lighting, please refer to the Light chapter in the DataMesh Studio User Manual.

7. Can you copy and paste sub-objects of the model in Studio?

No. In DatatMesh Studio, you can only copy the entire element as a whole.

8. Can you define the center point of an individual model in Studio?

No, Studio does not allow you to customize the center point for an individual element. However, when multiple elements are “grouped” or when multiple elements are selected, you can choose a public center or designate a specific element as the center point. For more information on center point settings, refer to the Multiple Selection and Group Elements section in the DataMesh Studio User Manual.

9. What are the differences between the three export options for scenarios?

• • Export Basic Scenario: The exported scenario file contains only the basic scenario file and does not include resource files. Note: To import and use this basic scenario file, you must have access to all the resources within the scenario.
  • Export Full Scenario: The exported scenario includes the basic scenario file and all related original resources (unaccelerated). Users can directly use the scenario after importing it, but resources need to be re-accelerated.
  • Export Accelerated Scenario: The exported scenario includes the basic scenario file, related original resources, and accelerated resource attachments. Users can directly use the scenario and accelerated resources after importing.

10. 10. How to unlock a file when prompted “Another user is editing the scenario” upon opening the scenario?

This message indicates that the scenario is currently being edited by a user and has been locked. Only the scenario’s creator or the current editor can unlock the file. To unlock it, go to FactVerse -> Digital Assets -> Resources, find the corresponding scenario file, and click the padlock icon.

11. Why can’t certain elements be deleted in Studio?

In Studio, due to the default inheritance between scenes, elements can only be deleted on the scene page where they “appear.” You can add “disappear” actions to the element in subsequent scenes, which means the element will not be displayed in later scenes.

DataMesh One

1. What are the prerequisites for event collaboration?

a) The company needs to enable event collaboration services.
b) Accounts participating in the event must be under the same enterprise account.
c) Accounts participating in the event have all been granted One-end Standard Mode permissions in FactVerse -> License Management.

2. Does scanning a resource code to view a scenario or model involve permission issues?

Yes, it does. If your account does not have permission to view a specific resource in FactVerse-Digital Assets, you will not be able to open that resource by scanning the resource code.

3. How to select child objects in editing mode?

In editing mode, you need to select objects layer by layer according to the model structure: Click once to select the parent level, click a second time to select the secondary level, and so on.

4. How many position codes can a scenario support at most?

A scenario supports up to 20 position codes.

5. Position code scanning error issues

Inconsistent placement direction: The placement direction of position codes is either horizontal or vertical. If the actual placement of the QR codes does not match the scenario settings, an error will be prompted.

Scanning QR codes not set in the scenario: Scanning position codes that are not set in the scenario will also trigger an error. For example, if the scenario is set with only 2 position codes, scanning the third position cod on DataMesh One will result in an error.

DataMesh Importer

1. Why can’t I open my model?

Unsupported model format: This may be due to model format incompatibility. Currently, the Importer primarily supports FBX and glTF format files, and is also compatible with OBJ, STL, 3MF, and PLY formats.

Model data loss: Data loss may have occurred during model export, which can lead to errors when opening the model in the Importer.

2. What should I do if the model only shows one side or is missing polygons after opening?

This issue is due to incorrect model normals. You need to return to the modeling software and adjust the normal directions.

3. Can you delete or modify child objects of a model in the Importer?

No. The Importer can only adjust nodes within the model structure when uploading the model, but it cannot delete sub-objects or modify them individually.

4. Why do substructure names in the model structure appear as letters or garbled text?

This is due to Chinese character encoding issues that occur during model export or conversion.

5. What should I do if the model is lagging or loading too slowly?

Large numbers of vertices and polygons or complex substructures can make the model file very large, affecting performance and loading speed. The model needs to be optimized for better performance.

6. Why is data missing after opening the model, such as materials or textures, and how should I handle it?

• • When exporting from Blender:

• • • Pack Data: Ensure you check the “Pack Data” option. When exporting to FBX, make sure to set the path to “Copy” to prevent texture loss.
    • Material/Texture Issues: If you notice that the exported model shows only one material or textures are misaligned, it’s likely because Blender defaults to naming UV maps as “UVMap,” which differs from C4D. You can resolve this by either unwrapping the UVs again or renaming the UV map.

• • When exporting FBX from 3DMax:

Ensure you check the “Embed Media” option to make sure textures and materials are correctly included in the export.

• • When exporting models from C4D:

Models should be converted via Blender to export as FBX or GLB format.

7. What is the purpose of checking model structure nodes in the Importer?

By selecting model structure nodes, you can selectively control the components of the model. When uploading the model, selected nodes will be uploaded as separate objects, while unselected nodes will be merged with other nodes.

DataMesh FactVerse

1. How many admin accounts can a company have?

Each company can have only one admin account. Depending on the service package purchased by the company, multiple FactVerse accounts can be created.

2. Can different accounts within the same enterprise view each other’s edited/uploaded content?

a) Different accounts within the same department can share resources in their respective “department” folders.
b) Resources in the “My Space” folder are only visible to the individual user.
c) Users can create new folders and set the public scope of those folders themselves.

3. What does accelerated service mean?

The FactVerse platform’s model acceleration service automatically optimizes uploaded models to enhance loading and rendering performance across various platforms. The larger the model, the more significant the benefits of the acceleration service; smaller models may not show as much difference.

4. When logging into FactVerse for the first time, the message “License is not assigned. Please contact your administrator” appears.

The company admin must assign departments, roles, and licenses to accounts within the enterprise management module of FactVerse. Once the assignments are completed, users will be able to access the corresponding permissions.

For more information on permission allocation, please refer to the User Permission Management section in the DataMesh FactVerse User Manual.

5. What is the difference between uploading a model using Importer and directly uploading a model on FactVerse?

• • Importer Upload: Allows users to select and upload specific model structure nodes as needed.
  • FactVerse Upload: The cloud server cannot recognize the internal structure of the model, so the model is uploaded as a whole resource to the resources. In Studio, this resource does not have a model structure.
