GLB does not trigger preview upload

[obxium]

Describe the bug

I minted an NFT with a GLB media file:

https://nft.kodadot.xyz/rmrk/detail/9050726-34BE282B68C3F03135-FLTS-FRACTAL_LOTUS_1-0000000000000001

The media is not present on any browser that I have access to (most contemporary browsers at latest versions). Instead it looks like this, showing only the KodaDot logo in place of the GLB.

The file in question, FLOW1.glb is approximately 38MB in size. I have used various tools, such as glTF Validator to ensure that the GLB file content is valid, and it is valid.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://nft.kodadot.xyz/rmrk/mint
2. Click on the Drop your NFT here or click to upload. We support various media types (BMP, GIF, JPEG, PNG, SVG, TIFF, WEBP, MP4, OGV, QUICKTIME, WEBM, GLB, FLAC, MP3, JSON) uploader
3. Complete required fields
4. CLICK TO CREATE NFT(S)

Observe that the finished NFT does not correctly display the GLB model.

Expected behavior

The GLB model content should appear within the figure element for the image-preview div.

Screenshots

Desktop (please complete the following information):

• OS: macOS 11.5.2
• Browser Chrome
• Version Version 93.0.4577.63 (Official Build)

Additional context

I also tried this on contemporary versions of other Desktop browsers to the same effect.

Looks like GLB does not trigger preview upload

@obxium :
The trick is that files (like mov, json) trigger additional field called poster/cover
then If this field is visible app automatically constructs JSON like

{
  "image": secondFile,
  "animation_url": file
}

If the preview upload is not triggered app constructs JSON:

{
  "image": file,
}

In GalleryItem.vue I only chceck the mimetype of the secondFile. Thus It fails on render.

But I think we can fix it without re-mint

Ahh makes sense @vikiival. Thanks for the explanation.

Is is possible then to use the GLB file again as the value to the poster/cover field in order to have it render in gallery view for the next ones I need to mint?

In gallery view, what would be super heavy on objects I guess as GLB objects are quite big, it's an option to have it.
If we can make it make it load on hover or something like that, that might work.
You want to save user bandwidth to not load 12x30MB+ files upfront :)

Makes sense, so what do I need to do to have it appear on the actual object page like here:

Just set the value in animation_url?

Yes this should work!

So time to solve it, somehow? 😄

Need to convince drop upload to spawn another drop upload for the second file

I was told on discord to post my report here ^^
