AR Graffiti App using 8th Wall

Technical Support

Hey everyone,

we’re working on a university project where we’re trying to build an AR graffiti app using 8th Wall, but we’re currently pretty stuck.

Our main issues are:

  • We can’t seem to find any (working) modules anymore, so we’re unable to properly add or integrate features.

  • A lot of examples and parts of the documentation seem outdated or structured differently than in the current version.

  • On top of that, we’re having major problems with VPS (Visual Positioning System) — we’re not sure how to set it up correctly or what requirements need to be met for it to work.

So we were hoping someone here might help:

  • Does anyone have experience with recent versions of 8th Wall?

  • Where can modules/components currently be found, and how are they supposed to be integrated?

  • Any common pitfalls or setup tips when working with VPS?

  • Are there good tutorials, sample projects, or best practices you’d recommend?

We’d really appreciate any advice or pointers. Thanks a lot! :folded_hands:

Hi!

That sounds like an awesome project! I’d recommend taking a look at our YouTube videos here: https://www.youtube.com/8thwall

Thank you for your quick response! :slight_smile:

We’ve actually already gone through several of the YouTube tutorials from the 8th Wall channel. However, we’re still having some technical issues:
•⁠ ⁠VPS Mesh: We created a verified VPS location and edited the mesh for sprayable surfaces. When testing it with the phone at the vps location, the mesh isn’t recognized properly, so we aren’t able to spray on it. We used following tutorial to integrate a VPS location: https://www.youtube.com/watch?v=2NLjDnfReyo
•⁠ ⁠Generating Objects: How can I spawn an object at a VPS location position, where the midle of the camera is pointing with a raycast (using the ecs.input.SCREEN_TOUCH_START event)?

Do you have any guidance or resources for these issues? We’re using 8th Wall Studio.

Thanks again for your help!
