Hi,
CoronaMTL absorption color defaults to 128 gray, which often gets converted to VrayMTL fog color by the converter. However, CoronaMTL also defaults to absorption being disabled (distance at 0) where as VrayMTL Fog multiplier defaults to 1, and converter doesn't seem to take this into account. As a result, pretty much every clear glass material converter from Corona to Vray using V-Ray's built in converter ends up gray or black.
Also, I believe that for every material converted from CoronaMTL, reflect on backside should be enabled, as Corona always reflects on both sides.
