Description

Spotted on @mramato's Mac Mini. The metallic surfaces show no reflection, just black.

Test URL: https://cx20.github.io/gltf-test/examples/cesium/index.html?category=tutorialModels&model=DamagedHelmet&scale=1.0&type=glTF

Not sure if this is an issue specific to this machine, or how general this might be.

Research direction

Start by opening the linked test URL with the DamagedHelmet glTF model and compare metallic rendering on the reported Mac Mini with another environment. Determine whether the missing reflections are machine-specific or general, then verify that metallic surfaces reflect correctly after the fix.
