VRM loading stuck at 99%

[l-117]

Hi,
When I try to load my VRM model in electron.exe, the loading gets stuck at 99%. I can see a tiny model in T-pose at the bottom of the display window, but I am unable to move or drag it. The model itself works fine in Warudo.

It's probably related to your VRM model. Click XR Animator tray menu (located at lower right of Windows taskbar), DevTools, Console tab, and see if there is any red error message.

Do you have a working vrm model example ? I've tried few from the web and one exporter from blender and I'Ve got the same error, on web or electron version.

For example, a model that is loading in https://3d.kalidoface.com :

MMD_SA.js:10344 TypeError: Cannot read properties of undefined (reading '0')

I understood the problem at MMD_SA.js:9110:75

If I understand, it is not finding the 'leftMiddleProximal' ?
para.left_palm_length = v1.fromArray(para.pos0['leftHand']).distanceTo(v2.fromArray(para.pos0['leftMiddleProximal'])) * vrm_scale;
