Tutorial: Live preview your VR content in DeoVR using Mistika
DeoVR now integrates with MISTIKA, giving creators the ability to preview stitched VR content directly inside the headset. This allows for real-time creative decisions with precise visual feedback.
What Is Live Preview?
Note: This is live preview only, not live streaming. It works by rendering one frame at a time, with a refresh delay of a few seconds after each change. This lets you inspect the stitch, alignment, and depth in headset before committing to a full render.
Live Preview Your VR Content via Port Forwarding
For a more dynamic and collaborative preview experience, DeoVR also supports live previews of VR content from Mistika using port forwarding. This method enables others to view the results in their own headsets by simply entering a provided link into the DeoVR app.
The process involves setting up a link in Mistika that incorporates your internal and external IP addresses, allowing the live feed to be accessible remotely:
For the purposes of this explanation, your internal IP address is 10.10.10.100 and your external IP address is 111.111.111.11
-
- In Mistika, you are given a link to use across your local network: http://10.10.10.100:8888/vr/manifest.dj3u
- Port forward your external IP address to your local IP. It should look something like: http://111.111.111.11:99999/vr/manifest.dj3u
- Now, others can preview your results in their headset by typing your link in the Deovr app.
Why It Matters
Live preview in VR removes guesswork during post-production. You can catch errors like:
- Misaligned stereo depth
- Stitch breaks or ghosting
- Incorrect camera orientation
By using DeoVR for review, you ensure your final product looks exactly how your audience will experience it.
Local Previews for Tethered Headsets
Initially, this powerful preview functionality is available for users with tethered VR headsets. The system works by having Mistika output specific frames as photo screenshots (currently supporting JPG and PNG formats) into a designated local folder.
Within DeoVR, users can easily navigate to this folder using the file browser, select an image, and then adjust the view angle and stereo mode as needed. A key feature is the automatic refresh capability in DeoVR; if a picture is overwritten with an updated version from Mistika, DeoVR will automatically display the new frame. This allows for an iterative and efficient way to review edits, with the ability to store multiple frames and swipe between them for comparison.
