Transparent element in glb

Support Materials and Textures
1

Blender 4.2

Hi,
I need to have a transparent material exported in glb.
it’s a plane that has no texture.
It’s just here to help placing some elements later on. It must not be visible in viewers (as in as if completely nonexistent: it should not influence lighting in any way, in a viewer or in a game). But it must be in the glb.

A transparent BSDF doesn’t make it when looking at the glb in the Babylon sandbox: it’s visible.
Neither will a principled bsdf with opacity set to 0.

How to make that happen ?

Thanks

This is likely a bug I’m gonna report now. It works if you plug a black texture in the opacity and export with textures.
