I just updated to .3 version it works great for 2.79! and decided to try it on Blender 2.80.5, I get an error(see attach image).

holp support blender 3.1

Can you write some instructions on how to use this?

It's possible that I don't fully understand Blender, but it's my understanding that gltf lets you store vertex colors in RGBA format while Blender only accepts vertex colors in RGB format. So the importer ends up discarding the extra alpha values of the vertex colors in a gltf file. Is it possible to stash those alpha values into a second vertex color attribute during import? So the importer would create a COLOR_0 and a ALPHA_0/COLOR_0_ALPHA or something like that.

It would like awesome to follow the nodes from glTF-Blender-Exporter here:
https://github.com/KhronosGroup/glTF-Blender-Exporter

The workflow: you export a model from substance painter in glTF, you import with your ksons/gltf-blender-importer, you animate the scene in blenber, and export with glTF-Blender-Exporter for ThreeJS, Unity or BabylonJS. Not need to replace the nodes.

I'm saving the .glb file from Modo 12 and trying to get a simple cube into Blender 2.79.1. Upon importing I get the following errors(see attachment) ,the cube.glb is also attached in the zip.

CubeTest.zip

Using the latest Blender nightly as of 3 May 2018, I installed the addon and importing a gltf gives the following error:
AttributeError: 'bpy_prop_collection' object has no attribute 'link'
This is in io_scene_gltf/node.py line 111 in create_root_objects.

This may be helpful: https://wiki.blender.org/index.php/Dev:2.8/Source/LayersCollections/API-Changes

Current importer relies on smoothing groups with normals discarded rather than carrying original vertex normals, will there be a plan to support it?

When importing in Blender a file that contains extras fields, that data is lost. Later if I decide to export the scene back to gltf, the custom meta is gone.

I am using both Blender 2.79 with Python 3.5 and Python 3.6, somewhat after installing add-on, I am not seeing it inside the Add-On Preferences. Thus I cannot enable it and cannot see the IO import.

Any pointer? Thanks!

I'd like to be able to import a scene including lights using glTF.

At line 139, it should be using roughnessFactor but it's using metallicFactor, and vice versa on line 146.

So i'm just importing a cube with no material or bones, but the importer creates an armature upon importing, is that normal? If so, it would be nice if it doesn't create an armature.

Any downloaded sketchfab GLTF won't import correctly. It's a mess of triangles

please add import global scale when import glb

Thanks for this addon that enable me to import the gltf into blender.
And now I am wondering if it could import gltf1.0 into blender. To start with, I try to change the code of searching way. Because there is a dict behind every main properties in gltf 1.0, while it is list behind the main properties. But it is quite difficult, and especially in creating the virtual nodes. I'm not sure if it is a good way.
And if there are already some ways to convert the gltf1.0 to gltf2.0?

ok so yes it works but i cant import armatures

on this one it simply doesnt import bones and on the bones branch it doesnt import at all

on the bones branch i get

  File "C:\Users\Flashlight Bulbton\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons\io_scene_gltf2222\__init__.py", line 116, in execute

the 2222 is because it wouldnt even install right for some reason (that was a fault on my end)

im trying to import a vroid vrm model

Hi! Is this an importer addon? I can't locate it inside the addon menu. Thank you!

When I try to install it using "Install addon from file" button in user preferences and pointing directly to the init.py it doesn't appear in addon's list.
When I renamed the file to glTF2Importer.py and the installed all appeared fine. So, I suggest to rename the file.

Blender version 2.79, Windows 10

I tried the animation glTF samples, e.g. AnimatedTriangle. When it's imported, I don't see any animation on the triangle's rotation (as specified in the glTF file) or any keyframes in the graph editor. I see in the import code it's doing something with the animation, I just don't know how to get that to actually animate.

When import VROID character (vrd -> gltf) the bone hierarchy comes as Empty, is there anyway we can import the bones but with weight and everything?

Thanks!

I've been trying to import a gltf+bin file but had no success. When I convert the file to glb it works fine.

Does the importer not support gltf+bin? If so, any chance this can be added?

Importing that model using the gltf-blender-importer 0.3.0 imports the cube, but no vertex colors are visible in the render. It does have a default metallicRoughnessPBR surface, so I'm not sure why the vertex colors don't show up.

Hey just wondering if vertex groups supported with this importer?, loaded in a animation but no vertex groups on the mesh.

unzips gltf-blender-importer-master folder in add ons folder instead of io_scene_gltf

There is a problem regarding shared accessors. If you have a single accessor containing all vertices for the .gltf file, but there are multiple meshes, then all vertices in that accessor will get loaded into every mesh. This is a big problem when you have a big .gltf with hundreds of meshes. For instance, we had a .gtlf with 150k tris, but when loading it, the importer would load 260 million verts because of the duplication. This caused Blender to sit at a whopping 10GB memory usage, in an empty scene with just that model.

Here is a simple example of 2 boxes. The caps are separate meshes, and the body is a single mesh. So 3 submeshes per box for body and caps, 48 vertices total in the accessor. This means 2348=288 vertices loaded in Blender, where we would only expect 48 vertices loaded.

This problem came to light when exporting using the Sketchup GLTF exporter by CentaurMare. This plugin puts all vertices in a single accessor to save a bit of file size. The author of that plugin was very helpful, and we had some back and forth to come to this conclusion. The author says he discussed the problem on https://gitter.im/KhronosGroup/glTF to check if shared accessors like that are part of the .gltf spec. Consensus was that it is, and so it should be a bug in the importer in Blender rather than the exporter in Sketchup. Maybe worth noting is that the official Unity GLTF importer exhibits the exact same issue as the Blender importer, I have made a report there as well.
