I'm adding support for spot and point lights in my app and noticed that they didn't show up. To figure out if I'm doing something wrong in my implementation, I've created a scene in Blender which I've exported to (binary) GLTF. I've attached the test files. Next, I used the gltf_viewer app and I'm not seeing the lights there either.
Screenshot from Blender:
Result in gltf_viewer:
Started like ./gltf_viewer ./assets/models/spotlight-test-v1.glb using a fresh build.
Output gltf_viewer:
