Request to revert to a previous engine

It seems reading several forum posts that having different engines per project is possible? How do we request such? Version 26.0.6.150s is causing flickering face tracking and we’d like to request going back to a previous engine.

Project link is 8th Wall

Hi @Stride9_Development , I have pinned your project to engine version 24.1.10.2165

Sorry for the issue and thanks for your patience while the engineering team investigates the issue further.

thank you. Will try shortly…

In the settings panel it indeed shows that the engine version is pinned to 24.1.10.2165, however when I start the app, the console log still states β€œ8th Wall XR Version: 26.0.6.150s” and so does console.log(XR8.version()). Can you please advise how to make the app use the pinned version?

The pinned engine version currently only works for the public URL. If you have a dev token on your device (from scanning the Preview cloud editor code, for example) it will override.

Can you do the following?

  1. Go to https://apps.8thwall.com/token and remove the dev token, if there
  2. Visit the public (published) URL of your project, i.e. App Not Available
  3. In the console logs I would expect to see the older engine version for that project.

Thanks!

It works, though I would not necessarily say this is an acceptable/workable solution. What good does it do if only the published version can be pinned to a specific version but not the preview/simulator/development? How can we efficiently test features that require a pinned version, but fail in the latest engine release? Is this expected to be β€œfixed” sometimes in the future or is this a limitation we need to live with?
