Colors or lighting are not exactly the same in Slicer and glTF viewer

Colors appear to be lighter, somewhat washed out in glTF viewers - see

It seems that the default image that is used for image-based lighting in 3dviewer.net makes the scene significantly brighter (washed out) than the models look in Slicer (without image-based lighting).

Potential solutions:

• Enable image-based lighting in Slicer: in Lights module (provided by Sandbox extension), click Select all, Default, Hospital room. Then set Interpolation to PBR in Models module and adjust Diffuse, Metallic, Roughness values. Specifically, try using Diffuse = 0.5.
• Use a darker image for image-based lighting in 3dviewer.net: click settings icon on the right, click on the image next to Environment, and choose a dark image, such as the evening in the park (lower-right)
