[3dsmax] exporting faulty glb due to albedo alpha

Bugs
1

Hi,

We have a problem with exporting a simple mesh that use an alpha, it’s a fence grid,

if you use a GLB viewer like https://gltf-viewer.donmccurdy.com/ , we get these errors:

basically, something’s gone wrong for that albedo alpha and its setup.

Is there anything we have to do inside 3dsmax to make this work? for example, exporting the same mesh using substance doesn’t create this error.

Thanks,

Jean

Adding the glb file now, because you have some weird restrictions for new users that we can’t add two links on a post… that’s a bit too much as restrictions…

here’s is the glb file itself if you want to check it.

@jeanfabre It looks like you are using an old exporter (v20200225.2). Can you try this on a recent one?
