import * as BABYLON from "@babylonjs/core/Legacy/legacy.js";
This will work exactly like the none ES6 version and the entire library will be included as a dependency.
Hey @Deltakosh / @sebavan
When I load the whole core engine, is there any advantage in using ES6 over UMD ?
Do you still get some kind of tree shaking ?
cc @ryantrem as well who masters the dark hard of module imports
If you really need to use the FILE LEVEL for the import to get tree shaking to really work.
How do you know what is the path to some of these classes in ES6 ?
I had to actually use devin.ai to search through the Babylon.JS source files and generate me
a Cheat Sheet with all the imports I use.
How does one find this out without searching thru the whole codebase looking for the actual file path to the classes?

I use vscode and Ctrl+p to find the file as it is the same name as the class most of the time.
As far as the original question, I guess that does not matter anymore.
I refactored my ES6 version using the above FILE-LEVEL imports and no longer try to use LEGACY to keep using the BABYLON namespace in pure ES6 projects
