The usual GLTF workflow is cumbersome: objects can only be found by traversal, changes are made by mutation, making contents conditional is hard. Gltfjsx creates a nested graph of all the objects and materials inside your asset, it will not touch or modify your files in any way. Now you can easily make the data dynamic, alter contents, add events, etc. 1️⃣ First you run your model through gltfjsx. npx allows you to use npm packages without installing them.
