I’m using Rhino 6.20 and V-Ray 4.00.01. When I change the Object material display to Rendering Material for Arctic Display Mode, the object turns somehow transparent/translucent while the material in V-Ray is set to be 100% opaque. Never encountered this before. Anyone know how to solve this?
Could you please download and install the latest V-Ray update (4.20.01) and see if this resolves the issue?
If the issue persists, could you please share the project with us so we can investigate in detail? If this is alright, please send us an archived copy (V-Ray > Pack Project) to support@chaosgroup.com via email or a file-sharing service of your choice.
Kindly be informed that we were unable to reproduce the issue in our environment!
