Vraymat script

Would be nice to have a tool to change multiple vray mat attributes on selected or all scene materials. I know there was a script on scriptspot, but thats old and hasnt updated with new materials. A tool from chaos would be pretty sweet.

If there is one already that works, can someone link me to it?

Cheers

hit F11 - the listener pops up. Keep in mind, he records now everything so have an eye on it, what happens there and find only the lines you need.
and do one or more change(s) on attributes of your mat.
Copy this snippet and paste it in e.g. as a new script in the Editor
Select all the Materials you like to alter with that and execute it…
if all is fine & you like to keep it, save it as a script.

Well Modifier Modifier ZORB pretty much does everything without having to update most of the time, but that makes it a little overwhelming sometimes. https://www.scriptspot.com/3ds-max/scripts/modifier-modifier-zorb

There are some scripts like MAXTools: V-RayMax Converter PRO that can also mass change some values, not sure only selected ones.

There used to be VMC but that’s probably the one you mentioned that’s outdated. https://www.scriptspot.com/3ds-max/scripts/vmc-vray-material-control
