Caching ClassVR Content
Applies to models:
CVR-155-A / CVR-255 / CVR-255-64 / CVR-355-128 (Xplorer) / CVR-655-128 (Xcelerate)
What is Caching?
Caching content allows you to pre-download files and tracks to your ClassVR headsets in advance, ensuring that content is ready and available when your lesson starts — even without an active internet connection.
This is especially useful for:
- Large files (e.g. 360° videos, 3D models)
- Lessons requiring smooth playback with no latency
- Classrooms with limited or variable Wi-Fi performance
Prerequisites
- Headsets must be powered on and connected to Wi-Fi
- Headsets can be in the charging case, but they must not be turned off
- Content caching will not begin if the headsets are powered down
How to Cache Content to ClassVR Headsets
- Log in to the ClassVR Portal:
https://portal.classvr.com - Click the gear icon in the top-right corner to open Settings.
- From the left-hand menu, select Subscriptions or go directly to:
https://portal.classvr.com/manage/subscriptions.cfm - Under Content Synchronization, click on a content channel (e.g., ClassVR, Avantis World Theme Park, etc.)
- Tick the checkboxes for the tracks you want to cache.
- Make sure the headsets are powered on and connected to Wi-Fi.
The selected content will automatically download in the background.
📌 Note: Downloading begins immediately, but large files may take time to complete across all headsets.
Tips for Lesson Preparation
- Cache content the day before your lesson to ensure everything is ready.
- Use the “Preemptively Download Playlist” option from the Portal when sending custom playlists to ensure files are cached ahead of time.

Troubleshooting Caching Issues
Content is taking a long time to upload
- Check your network speed and stability.
- Uploading large files to multiple devices may take several minutes — plan ahead.
Some content is missing
- Only 20 tracks are visible at a time on the headset’s main screen.
Additional content is still on the device and can be pushed from the Portal.
Storage space is full
- If uploading large quantities of content, reduce the number of tracks or clear older content first.
- Check storage via the Info icon on the headset.
Custom content isn’t displaying
- Make sure your files are in supported formats. See:
Supported File Formats
Not all headsets received the content
- Ensure all required headsets are:
- Powered on
- Connected to Wi-Fi
- Have sufficient available storage
- Allow enough time for all headsets to complete the download. Content pushes are not instant across large deployments.
