Hi Luis,

That error vaguely looks like you’re using browser imports. Are you transpiling your scripts via a bundler like webpack, or are you just loading your scripts directly in the browser? If the latter, then I would recommend checking out the [ES6 tutorial for vtk.js](https://kitware.github.io/vtk-js/docs/intro_vtk_as_es6_dependency.html). (Note there is currently an issue with those instructions that was resolved here: [Problem when trying to setup first VTKJS project](https://discourse.vtk.org/t/problem-when-trying-to-setup-first-vtkjs-project/4761/6)).

As for the 5th part of the course, that video wasn’t recorded due to time constraints and available personnel to cover that material. As a possible substitute in the interim, I can highly recommend [webgl2fundamentals](https://webgl2fundamentals.org/) if you wish to understand more of the underlying WebGL tech and GLSL shader code.
