I get an error at the following notebook, and I honestly don’t have a first guess as to the cause:

> **[Untitled](https://observablehq.com/d/041f71faeef77188)**

especially because I’m basically just trying to mimic this example:

> **[Three.js](https://observablehq.com/@observablehq/three-js)**

by reproducing it one cell at a time. So as far as I can tell, I have basically just done exactly what is done at the working notebook, except that I’m only halfway through the development.

I even tried commenting out code in the working example to make it like my notebook, and the working example continues working … so I’m super stumped. I’ve searched for spelling mistakes or small differences in the two notebooks, and maybe I’m just missing it, but I can’t see any differences (especially after editing the working example to look more like my notebook).

More recent versions of Three.JS no longer support the UMD format for examples. Have a look at this thread for alternative approaches:

> I’m trying to learn Three.js. It looks like the newest version of three only uses ES6 modules in away that the standard example by Observable doesn’t support. I tried a number of things before I found something that seems to work. Is this the correct way to get it going in ObservableHQ?
