Hello：

I have completed the project migration work. The World Effect project is working without issues, but the Target Image project isn’t functioning properly. I suppose the Target Image project might need to generate feature files to work, right? However, I haven’t come across any tutorials on this aspect so far.

Oh I see:

need not generate image feather file, add this code in app.js

const onxrloaded = () =\> {

```
XR8.XrController.configure({

  imageTargetData: \[

    require('../image-targets/day.json'),

    require('../image-targets/night.json'),

  \],

})

```

}

window.XR8 ? onxrloaded() : window.addEventListener(‘xrloaded’, onxrloaded)
