Hi, I’ve used Babylonjs for several projects, I’m also an Unreal Engine 4 developer and have big interest in the ability to export glTF directly from Unreal Engine and use directly in BabylonJS.
There is an open source project that supports this for PlayCanvas (GitHub - ue4plugins/GLTFWebViewer) which has a few extensions that allow enhanced rendering, including extension for lightmaps.
I’m no expert in BabylonJS to understand how to implement these extensions myself. Anyone can shed some light on how to tackle this task? I’m mostly interested in the lightmap extension.
