I’m not sure “match” is the right name, because I use the german version. I mean the lowest button at the Rhino material properties page. It match the Rhino material properties, but dosn’t assign the Vray material from on object to the other.
Small question for interest: do we get a material editor in the next time?
We’ve asked the people at McNeel if the match button is supposed to copy our materials, and I believe they said it doesn’t. We can look into it again I suppose, but I’m pretty sure thats a Rhino limitation
