Rougness map not rendering properly?

Hi Verge,

I have two scenes, one from Verge export (both Blender) and another from our internal build which is adding some automation and js.

I am trying to identify why is rougness map causing “wetness” on our object:
– first, correct look with rougness
– second, incorrect “wet look” is attached

I have tried so far without any luck:
– made sure scenes and materials are identical
– disabling all additional javascript including postprocessing puzzles etc
– disabling texture compression
– made sure everything is loaded properly
– tried changin V3D Engine version (kept newer in second build)
– made sure its not device-specific nor browser-specific
– changed HDR background

Can you help me identify what might be causing this problem? It has been bothering us on all projects.

thank you very much in advance for any suggestions!
