Unknown command: _visMatEd

Receive the following error when attempting to run vray.

“Command: _visMatEd
Unknown command: _visMatEd”

I assume this is perhaps a corrupt vray install, but our school IT admin isn’t too bright not to allow students with minimal administrator rights.

Hi, Clark
All ‘vis’ commands were renamed to ‘vray’ commands in version 3.60. I suppose you’re not writing that command yourself, but using a button command. If that is from the V-Ray toolbar, I pretty sure you’re using the wrong toolbar file. In this case just load the .rui file from the V-Ray installation folder.
If you have this error as a result of a script or macro, just change the command prefix
