ColladaLoader: Error while parsing/building skeleton

[jadutter]

I asked stackoverflow, and the first comment suggested it may be a bug that I should report.

I give a detailed report in my post here:

https://stackoverflow.com/questions/48796931/why-cant-colladaloader-js-from-three-js-load-my-file/48797863#48797863

And here's extra relevant info not mentioned on stackoverflow.

Chrome requesting http://127.0.0.1:5000/raptor

Flask web server returns raptor.html that imports three.js and ColladaLoader.js and contains the script to import the raptor.dae.
Substituting raptor.dae with the elf.dae from the demo works.

Everything I've done is self taught, and this issue is just the one obstacle where I don't have the knowledge to solve it, let alone the minimum amount of knowledge to search for the answer.
Any guidance I can get would be greatly appreciated.

I see multiple problems with this dae model. Investigating...

Your model should now load with the latest dev version of ColladaLoader. But there is still one problem in context of skeleton parsing. I'll provide more details as soon as i know what's going wrong.

I've loaded the dev version of three.js and ColladaLoader.js
Elf.dae still loads, and Raptor still does not load.

The raptor file is ripped from Ark Survival Evolved and I found it online.

Let me know if there's anything I can do to help.

Elf.dae still loads, and Raptor still does not load.

Yeah, you're right. I've added a change to my local dae file and that solved the issue 😅

The problem is that the file refers to the skeleton in an unusual way. It does not refer to the top most bone but to the node of the visual scene. ColladaLoader can't process this setup at the moment. If you change the following section from

<skeleton>#ID8</skeleton>

to

<skeleton>#ID9</skeleton>

the file should actually load (ID9 is the id of the top most bone whereas ID8 is the id of the visual scene).
