I cloned this project and read their codes.

However, I couldn’t find that vps-shader had been added or used.

I think it’s need to add some code for Procedural Location or something to show a rainbow wireframe.

```auto
## How It Works

1. The user navigates the 3D world map where VPS locations are represented by spheres.
2. As they approach a VPS Location, the sphere transitions into a rotating disc with a thumbnail image.
3. A UI overlay appears, showing the location name and a "Start AR" button.
4. Clicking the button loads the corresponding VPS procedural AR experience.
5. In the AR experience, a rainbow wireframe effect is overlayed on the detected VPS location mesh.

```

Hi, welcome to the forums!

Good catch, I’ll update this sample project asap.
