(Please help!) I am having Issue with Marmoset viewer, not Marmoset.

I had a weird issue with Marmoset, everything looks and works just fine in marmoset, the screenshot looks fine, turntable looks fine, But when I exported it to Marmoset viewer, the whole thing is very shiny, somehow roughness is messed up in viewer. 
Any idea why?

Be sure to check the errors on in the export window. It looks like you don't have shadows in the Viewer version. If you're using omni lights, shadows will not be available in Viewer. You'll want to use spot or directional lights instead.

The error log may provide more information about other unsupported features. If you're using area lights (light width greater than 0) this can have a big effect on the specular highlight size, which can change the perception of the glossiness of the material.

You can find a list of the supported features here: https://marmoset.co/support/?page=viewer
