Getting an {“isTrusted”:true} error when using GLTFLoader

问题

QUESTION:

Everything was working fine: I converted my FBX files to GLTF inside my /GLTF/ subfolder.

Sadly, some geometry was missing from some of the converted files, so I tried to convert again my FBX files, this time to /TEST/.

Suddenly, the models don't load and from my console.log statement:

console.log( 'An error happened: '+JSON.stringify(error) );

I get this strange useless error:

An error happened: {"isTrusted":true}

So I try to convert my FBX files to .glb instead, this time to /TEST2/ and add an additional console.log statement:

console.log( 'An error happened: '+JSON.stringify(error, ["message", "arguments", "type", "name"]) );

I still get the same error:

An error happened: {"isTrusted":true}
An error happened: {"type":"error"}

Loading the first converted gltf files still works (those from /GLTF/), but as mentioned, some seem to have improperly converted: some of their geometry is missing.

What are those errors and how can I make my models load ?

NPM PACKAGE I USED TO CONVERT FROM FBX TO GLTF:

ERROR:

WHAT I LOOKED AT:

Log shows Error object: {"isTrusted":true} instead of actual error data

.NET Cors isTrusted: true error with Angular 5 app

{"isTrusted":true} exception in core.umd.js

EDIT:

回答1:

To debug this, you can drag the model into my debugging viewer and you'll see this message:

Missing texture: M_Med_Soldier_Body_BLACKKNIGHT_n.tga

Neither glTF nor web browsers support TGA textures, so the fact that it's referenced is a bug in the tool used to create this file. I'd recommend filing a bug on FBX2glTF.

However, if you look in the model folder, you'll see that same image is already there as a PNG (perhaps FBX2glTF converted it?). If you open the .gltf file in a text editor (I used Sublime Text) and search for "images", you'll find that incorrect TGA image reference. Rename it to .png and you'll see what I assume is the correct result:
