include GLTFLoader and ObitControls in rollup

I’m configuring a special build to modify the rollup file since some of my customers sill use an old browser in a WinXP S.O.

I modified browserslist to include Chrome version 50 or later which is correct now.

I also would like to include GLTFLoader so that can be compatible with Chrome (current version is not)

how to include GLTFLoader within rollup config?



use three.js to export or rollup.config.js,


I have tried several ways but none of them have worked.

tried this in Three.js, but the entire file is broken

export { GLTFLoader } from ‘…/examples/jsm/loaders/GLTFLoader.js’

Additional context

I’m using umd configuration
