@treefiddy , here are the tutorials for using Babylon JS on-chain. The entire API is already on-chain... all you have to do is use it as explained in the tutorials below (sorry, these are in no particular order). Everything in the code is fully commented so you know what each piece does.
This isn't really a step-by-step, but I know you'll understand the principles. And I can answer any questions you have.
