Lightmap not wrapping around model

I have created a scene in blender, and tried exporting the scene to show in babylon js. But no matter what I do, I can’t get my lightmap to wrap around the model. I have tried flipY and various other things, but I am wondering if the solution depends on how I exported my GLB model perhaps? I’m running out of ideas, and anything would help gravely.

Hello! It looks like you exported one lightmap texture for the whole scene, so you’d need a separate set of uvs on the meshes to account for that?
