demo resourses not work in example htmls

[sdarpeng]

I cloned the res pack and found some of them works well but more of them even not work.

1,works well:
tina / ligerZero / toru / trex / vegeta / xboxavatar_dehvor

2, works,but renders only one part of the gltf.scene
ahsoka_tano / cattus / tyranitar
all these 3 gltf files has moran than one part , the gltf parse function ignored the other parts?

3, not work
1),at_rt /cherubbotpm1 / gine / jinx / ronin /
everything is OK in blender but shows the following error:
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'idx')
Uncaught (in promise) SyntaxError: Unexpected token a in JSON at position 6
Uncaught (in promise) TypeError: Cannot read properties of null (reading 'joints')

2), readplayerme
everything is OK in blender but shows the following error:

3),companioncube / sword_war

UtilArm.js:34 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'getSkin')

4), suzanne

I find out maybe something wrong in threejs/lib/UtilGltf2.js

while the sub-objects of gltf file >1, there need another parser to resolve file, but failed.
This may caused gltf parts disappeared.

This is very old, new work in in ossos_next, so this can probably be closed.
