@mrdoob - I'm not seeing the issue, either. Can you reproduce it? What kind of lighting setup were you using?

Here's what it looks like with some directional lights:

I check in index(default example), it occasionally reproduces

add this into window.MODEL_LIST

'SheenWoodLeatherSofa': {
    url:'https://raw.githubusercontent.com/KhronosGroup/glTF-Sample-Assets/SheenWoodLeatherSofa/Models/SheenWoodLeatherSofa/glTF-Binary/SheenWoodLeatherSofa.glb',

Here's the corrected file url that worked for me:

Interesting - in addition to textures sometimes not working I'm seeing that an error is occasionally hit when building the merged geometry, which is odd. I wonder if there's some kind of loading race condition here? This will need a bit more digging.
