Hey, (@Drigax)  
Exporting a mesh to GLB or GLTF, without a texture in the material, fails to export UV channels…  
is this a bug or a gltf feature? 🤔  
slightly annoying when trying to attach a texture after loading the file 😄

Currently its a feature. We wanted to minimize the size of the exported scene if it has unused elements like UVs.

Is there a flag to enable UV in GLTF exports now? @Drigax
