ArgumentNullException occurs when trying to load some models

[parseccentric]

This blocks the model from loading and thus the session from proceeding.

v0.2.0

GearBoxAssembly

This appears to be a known issue with Siccity/GLTFUtility.

ArgumentNullException: Value cannot be null in build but not in editor.
This is most likely due to shaders being stripped from the build. To fix this, add the GLTFUtility shaders to the Always Included Shaders list in Graphic Settings.

Weird so, I cannot get GearBoxAssembly to import in the editor, the asset also does not open for me in the 3D Builder app in windows. I pinpointed the issue to Importer.cs within Siccity.

Task<GLTFObject> deserializeTask = new Task<GLTFObject>(() => JsonConvert.DeserializeObject<GLTFObject>(json)); deserializeTask.Start();

deserializeTask status comes out as Faulted, and the call to "deserializeTask.Result" brings up the error ArgumentNullException: Value cannot be null

This happens before Siccity starts looking for properties (i.e. materials to link shaders to) within the file.

Thanks for narrowing this down. Odd.

GLTFast comes back with this informative error: (dev/b01cb42 commit)

Maybe it is just a faulty model. I need to do some further testing when I have time, which will probably be just validating the model.

But we do still need to catch errors and load an error GameObject instead of halting; I can focus on that.
