@ntxdave said: I think if you look on this forum and the Sketchup forum you can/will find that others have had a similar problem with VRAY but I did not look at the resolution since I do not use VRAY. You are 100% right, I did not look hard enough. Recent update to the Library fixes this issue. Thank you! https://sketchucation.com/forums/viewtopic.php?f=401&t=68154&p=662293&hilit=vray#p662293
