Model Target Generator doesn't support GLB

January 12, 2021 - 4:19am #4

Hello all,

I'm working with model targets for my thesis and my current workflow makes heavy use of GLB files (glTF 2.0 binary format).

There are many external reasons why I chose this format but, regarding Vuforia, I chose it because the MTG app listed glTF 2.0 as one of the supported formats.

However, I'm using version 9.6.3 and it seemingly doesn't allow me to upload GLB files. I find this rather odd, since GLB is incorporated directly into the glTF 2.0 specification and it should be safe to assume that supporting glTF 2.0 also means supporting GLB.

Therefore, I just wanted to know if this is some sort of bug, or if MTG just doesn't support GLB right now. In that case, I'd like to know if there are any plans to support GLB files for MTG in the near-future.

Model Target Generator doesn't support GLB

Hi,

The supported file extensions for MTG are: pvz’, ‘gltf’ v2, ‘dae’, ‘fbx’, ‘igs’, ‘iges’, ‘obj’, ‘stp’, ‘step’, ‘stl’, ‘sla’, ‘wrl’, ‘vrml’.

Could you please let me know the error that you get?

Also would it be possible to share with us the glb file used?

Thank you.

Hi,

Sorry for the late reply, must've forgot to turn on notifications...

It doesn't show any errors, it simply doesn't allow me to choose any .glb files in the file browser because they don't show up. It only shows .gltf files.

I'm sending the glb file as an attachment.

Thank you for your help!

Hi,

Thank you for the zip file.

I also tried and was *not* able to add it to the Model Targets Generator.

This being said, I checked with the dev team and we currently do not support the glb format yet. The good news in our next release 9.7 we will support it, which should come out end of this Month.

In the meantime if you need to use the glb file, you will need to convert it to a gltf 2.0. This can be achieved for example by using vs code and glTF Extension.

Thank you for your understanding.
