使用 GLTFLoader 时出现 {“isTrusted":true} 错误 [英] Getting an {"isTrusted":true} error when using GLTFLoader
问题描述
问题:
一切正常:我在/GLTF/子文件夹中将 FBX 文件转换为 GLTF.
遗憾的是，某些转换后的文件中缺少一些几何图形，因此我尝试再次转换我的 FBX 文件，这次转换为/TEST/.
突然，模型无法加载，并且来自我的 console.log 语句:
console.log('发生错误:'+JSON.stringify(error));我收到这个奇怪的无用错误:
发生错误:{"isTrusted":true}所以我尝试将我的 FBX 文件转换为 .glb，这次转换为/TEST2/并添加一个额外的 console.log 语句:
console.log( '发生错误:'+JSON.stringify(error, ["message", "arguments", "type", "name"]) );我仍然遇到同样的错误:
发生错误:{"isTrusted":true}发生错误:{"type":"error"}加载第一个转换后的 gltf 文件仍然有效(来自/GLTF/的文件)，但如前所述，有些文件似乎转换不当:它们的某些几何图形丢失了.
这些错误是什么以及如何加载我的模型?

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:
https://www.npmjs.com/package/fbx2gltf
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:
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:
