The lights in KHR_lights_punctual seem too bright

[cx20]

I tried to display the sample model of KHR_lights_punctual with some glTF Viewer and compare it.

I think the Khronos glTF Sample Viewer is too bright compared to other viewers.

Thansk! I have confirmed that the glTF Sample Viewer resolves this issue.
