Error no longer occurs

[Mrgove10]

How did you manage to fix this ? (using the UPM)

[Siccity]

I don't know what exactly fixed it, but I tested import with the newest version from the master branch.

[Mrgove10]

When importing a model GLB i get

Siccity.GLTFUtility.Importer.LoadInternal (Siccity.GLTFUtility.GLTFObject gltfObject, System.String filepath, System.Int64 binChunkStart, Siccity.GLTFUtility.ImportSettings importSettings, Siccity.GLTFUtility.GLTFAnimation+ImportResult[]& animations) (at Library/PackageCache/com.siccity.gltfutility@9c5adcf7d6d816de1b974c2863290f23491c1f13/Scripts/Importer.cs:206)

https://github.com/Siccity/GLTFUtility/blob/9c5adcf7d6d816de1b974c2863290f23491c1f13/Scripts/Importer.cs#L205-L207

That line is item.Dispose(); Perhaps it is null? Try changing it to if (item != null) item.Dispose();

[Mrgove10]

That seams to have fixed it ! Tho when I import objects they apear in the hierarchy but they do not render, like if the object was a single point.

If i can get it working I would also like to do a PR to add examples.

[Siccity]

That was a workaround though. item is not supposed to be null. Can you send me the file that produces the error?

[Mrgove10]

It depends on the file. If use the same file as the original issue

I get this error :

I also tried with the example file from Khronos : https://github.com/KhronosGroup/glTF-Sample-Models/blob/master/2.0/2CylinderEngine/glTF-Binary/2CylinderEngine.glb

In that case no errors but nothing renders

I can not give you the original file because it is a payed asset sadly. But the issue (nothing rendering) is exactly the same as with the example file from Khronos.

Any news on this issue ?

Hi @Siccity I am facing the same issue while importing a gltf file. I am trying to import the same gltf file(not .bin file) that is on (https://github.com/KhronosGroup/glTF-Sample-Models/tree/master/2.0/GearboxAssy/glTF) but from a different server. The error is:

Any solution to this problem?
