Thank you for the report, Jenna!
What just happened?
Comparing a model in-world with a reference viewer, the in-world rendition of the object has a sheen applied, aforementioned sheen appears to be unexpectedly powerful as it is not being attenuated by the roughness map. See attached images - "expected" is the rendition from the reference viewer, "actual" is the SL rendition. "JennaMidday 103" is the HDRI used to replicate lighting conditions
What were you doing when it happened?
A / B testing a glTF between a reference viewer ( https://modelviewer.dev/editor/ ) and in-world, under the same (or as close as possible) lighting conditions.
Can also be reproduced in the Khronos Sample Viewer ( https://github.khronos.org/glTF-Sample-Viewer-Release/ )
What were you expecting to happen instead?
Sheen would be attenuated by the roughness map, as seen in the reference viewer.
Other information
Sheen has other issues, but this is the only one I've positively confirmed so far.
