I am a noob. Can someone help me with this?

First: the script is named ZZZZZZZZZZZZZ.js, so I can find it more easily.

When I do:
node .\ZZZZZZZZZZZZZZZZ.js

I get:

SyntaxError: Cannot use import statement outside a module

(node:13604) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)
D:\HASHLIPS NFT NFT NFT NFT\Hbargutangs XXXXXXX - Beta prkt\gltf-import-export-master\ZZZZZZZZZZZZZZZZ.js:3
import { ConvertGLBtoGltf, ConvertGltfToGLB, ConvertToGLB} from 'gltf-import-export';
^^^^^^

using .mjs on index.js doesn't change anything. Doing "type":"module" in .json is not relevant. What to do?

First off: Thanks for making this available!

I am able to clone the repo and build the project using "npm i" and then "npm run build", which produces a dist folder full of js and map files, but I don't see how to generate and/or run the command line tool. Do you have any hints on how to proceed?

You describe the 2 functions in the readme, but I think you mixed up the function names that begin the 2 paragraphs.

Whenever I use this model : tree.zip

The material on it isn't converted and does not show up in the gltf file. Using an online service to convert the glb to gltf, i noticed that the file uses two extensions :

"extensionsUsed": [
        "KHR_materials_volume",
        "FB_ngon_encoding"
],

And the material shows up correctly

"materials": [
        {
            "name": "material"
        }
    ],

Any idea why ? :D

Hi @najadojo, looks like the glTF 2-cylinder engine sample model got accidentally published with the last npm release.

The npm 1.0.18 release was 52kb, and the npm 1.0.19 release is 1.89 MB. The size difference is a new file "2c.glb" that looks to be one of the sample models.

Not a big deal, but would be nice to recover the space in a future version.

Hi

I was trying this exporter out, but it seems that it doesn't have typings module for Typescript. When I did npm install --save-dev @types/gltf-import-export I got a 404 not found.

Are there any plans on making one available?
Thanks in advance.

Kind regards

Hi @najadojo, hope you're doing well! Here's a suggestion from @rawnsley and Mozilla Hubs.

During GLB to GLTF conversion, it might be good to preserve the mimeType field, at least for types that are unknown to the guessFileExtension function. This would enable RGBE environment maps that Hubs has an extension for. Even if these files got a .bin extension, they would have a MIME type applied.

when i used this tools in nodejs +vuejs ，it has accured a mistake ,it show that fs.readFileSync is not a function

when i find the problem in the code file exportProvider.js, the fs modules has not installed.
could u give me some sugestion

Issue KhronosGroup/glTF-Blender-IO#61 talks about Blender exporting GLBs with base64-encoded data URIs in the JSON part. This doesn't strike me as the ideal way to structure a GLB, but, it looks like the glTF ecosystem may have some number of these in the wild already.

It looks like the GLB importer here fails to load these, producing an empty .bin file and "byteLength": 0 in the resulting glTF.

Sample model from that issue: glb_cubes.zip (use _io_2_79_cube.glb)

Converting some GLTF file to GLB results in an error.
The GLTF file is the output of COLLADA2GLTF.
The original DAE file is the output of Maya.
