Commenting here as I'm a bit confused; I only see a single FBX that has all the models in it; is there somewhere that has separate FBX files per model?
Viewing post in Modular PSX Architecture Kit comments
It’s a single parent FBX to keep them grouped and share import settings but all the objects are separate as children inside of that. There’s a Unity Package included with all the objects separated and prefabbed. If you aren’t using Unity then you’ll need to set up the objects in whatever engine you’re using yourself
How could I export them as separate glb/gltf files?
