Are you able to share a demo of the scene?

Confirmed the issue.

Here's what I think is causing the problem: the material component uses a default alphaTest of 0, whereas three.js uses a default of 0.5. That would be fine (both are reasonable values), but THREE.GLTFExporter has to choose _either_ opacity or alphaTest to write, it cannot export both to glTF. Because alphaTest appears to be non-default, compared to three.js, alphaTest is chosen.

The workaround would presumably be to set alphaTest: 0.5 on the model, but that isn't fixing the issue for me on a quick test. Will need to look more closely at why that is.

any news?

Transparency export is working for me with the master branch of aframe-inspector. I think we just need a new release to update it. In the meantime, adding a custom build of the inspector to your scene will work around the problem:

<a-scene inspector="url: https://aframe-inspector-20181128-abjyfktcpl.now.sh/aframe-inspector.min.js">
