Hi @rdeioris, I'd like to ask for advice on the best way to inject user data into a gltf file and have that accessible within UE.

My intention is to add metadata to a node, or perhaps even a mesh:

E.g.

"nodes": [
        {
            "mesh": 0,
            "name": "Hose_low",
            "userdata": "A<<B"
        },
...

"meshes": [
        {
            "primitives": [
                {
                    "attributes": {
                        "POSITION": 1,
                        "TANGENT": 2,
                        "NORMAL": 3,
                        "TEXCOORD_0": 4
                    },
                    "indices": 0,
                    "material": 0,
                    "userdata": "A<<B"
                }
            ],

In either situation, I was thinking that perhaps it would be exposed in Component Tags?

Is this possible right now? Or perhaps there is another way of doing it?

Thank you!

Invalid model binding click event after dynamic loading

I'm trying to put collision on my model, my model has many nodes, and I don't know how to put the model in the outer, since I've tried many things and it always crashes.

Blueprint: https://blueprintue.com/blueprint/dz_072p0/

I would like to know the difference between these two methods. The glb I loaded in UE cannot be played. Can you provide a screenshot of the blueprint,
I found that this glb has been parsed as nodeAnimation, but it cannot be played no matter what

Hello,
We need some documentation on how to use the save to package feature.
Best,

Hi team,
First of all, many thanks to your glTFRuntime plugin.

Recently, I downloaded and tried compiling it in Unreal Engine 4.27.

It has compile error in glTFRuntimeParserStaticMeshes.cpp and I moved error line:
VertexInstanceUVs.SetNumChannels(NumUVs);
into ENGINE_MAJOR_VERSION > 4 macro block.

Please patch this one line code fix.

By the way, I am a C++ developer in 3D graphics engine, but a newbie using GIT (github).
I uploaded my project using glTFRuntime. https://github.com/odyssey2010/unreal_gltf_runtime_scene
If any question, please contact me [email protected]

Thanks and Best regards.

I have two characters with identical skeletal structures. When importing using the plugin, I chose the skeleton that was already imported into Unreal Engine for one of the characters, and it successfully loaded the character. However, the animation blueprint that was created with that skeleton in UE is unable to drive the SkeletalMesh that was imported by the plugin.

is it possible to Replace the head between two ReadyplayerMe model by glfTFruntime? without changing skeleton assert and blendshape.

As far as I know, ReadyplayerMe model is combined by several parts, including head, hat, cloth, etch.
now I want to load model separately. I want to use first model‘s body and second model's head.

When loading skeletal mesh, I hope check enable per poly option.

Hi, I just a new beginner on your glTFRuntime plugin(a great project for me at least). I tried a lot of models with it, then I found this one 'BrainStem' its materials can't be rendered properly and I can't find why. Could you help to look at it?

BrainStem model url: https://github.com/KhronosGroup/glTF-Sample-Models/raw/main/2.0/BrainStem/glTF-Binary/BrainStem.glb

BTW, Can you consider to add some smoke tests or sanity tests at least covering all these Khronos sample models?

Thanks.

thanks for work,can your add support runtime load camera from gltf?thanks

On loading Static Mesh from gltf asset i check the "allowCPUaccess", "Build Complex Collision", and "Use Complex Collision As Simple" options. My Line Traces go straight through. If i also check the "Build Simple Collision" it starts to use this simple inaccurate collision even though "Use Complex Collision As Simple" is still enabled. Screenshots Attached. Thanks in advance

Even when including glTFRuntime in additional asset directories to cook, the materials are not always found. Instead of hard pathing to the directory of the plugin the materials, they should probably be registered with the asset manager or something.

I buyed this plugins ,but i dont know how to use in my work. I DownLoad some gltf from Sketch.com or Export from UE4, then
Called glTFLoadAssetfromFileName failed. here is the Error: LoadPrimitive(): Unable to load POSITION attribute.

Why the loaded model has more vertices than the original model
