Hi all,
I’m having a problem when I try to convert vray scene to a corona one. I’m using the CoronaConverter 1.42, and renderer is set to Corona. I’ve already tried resetting 3ds max’s settings.
Open for any ideas or suggestions 
Sooooooo… what’s the problem you are running in to?
The error message: Material type ‘missing material’ is not supported. Offending material …
In the render the object is red, as when you have unsupported material.
It happens when I import 3d trees, that are Vray scenes. However, I ran Relink Bitmap script, and there should be nothing missing. I also know that these particular objects work perfectly.
Hmmmm. Can you open the tree’s file and try saving it as a new file, then try converting the new file?
I tried doing that, but it didn’t help.
I don’t have vray on 3ds max - could that be a problem?
Yes! You can’t convert from Vray to Corona without Vray installed. The demo is enough, even when it’s expired.
I also tried with any of the 3d models I have, always the same problem.
Some of them are vray scenes, but even when I just grab the object I need and export it, it doesn’t work.
Very peculiar…
Yes, V-Ray needs to be installed for the converter to work, as PROH mentioned. That can be the demo (and, if I remember rightly, it can also be the demo after the trial period has expired - but V-Ray does need to be on the machine for the Converter Script to work).
Thank you all for the help. I installed vray and now everything works fine. Problem/ mystery is solved!
