My first attempt at showing some .obj models created awhile ago, using three.js. So, a complete and total three.js and WebGL n00b, but with JS experience.

I followed [this tutorial code](https://manu.ninja/webgl-3d-model-viewer-using-three-js/), but updated the libraries to the latest from the thee.js repo.

I’ve already worked through a few errors, but this one is persistent, and the [similar questions I can find on StackOverflow](https://stackoverflow.com/q/20090219/123033) don’t help.

My [repo is here](https://github.com/DaveEveritt/js3d).

What happens if you remove these lines?

```auto
materials.materials.default.map.magFilter = THREE.NearestFilter;
    
materials.materials.default.map.minFilter = THREE.LinearFilter;

```

Commented these out, and it works, thanks! Remaining issue is one of scale - I’m right inside the bowl and it’s too big, but I guess that’s something I can tinker with now.
