glTF File Will Not Load 1 Texture

I’m importing a glTF file but I’m having issues with a texture not loading. Specifically, the cloud texture in my Earth model. Here’s my Blender file:
earth.blend (2.0 MB)

Can anyone tell me what I’m doing wrong? I’m using https://gltf.report/ and the other textures are showing up but the one.

The “Add” node will not export from Blender, you’ll need a single texture per socket on the Principled BSDF. See:

https://docs.blender.org/manual/en/latest/addons/import_export/scene_gltf2.html

Ahh, thank you that worked! I’ll have to play around with this.
