The converter is unable to read/convert materials and maps from Vray unless you have Vray installed.
In the past, this issue was solved by installing the Vray demo, and even after it expired, the converter could use it to read Vray materials.
Since Chaos changed their policy, Vay is now a one-time trial, and it's not possible to download it again once your trial has expired.
This poses a problem when you update 3dsmax or get a new computer, since you cannot download Vray again. I see no other option than having to buy the full version of Vray... which really isn't worth it to me. This does imo defeat the purpose of the converter, rendering it useless.
Do you see any other solution? I think Chaos ought to be able to include the files necessary to make the converter fully functional without having to install Vray.
