HEllo,

I read some threads about material override and mantra, Especially the threads talking about the command “mantra -P”

I wonder where to put the script called by the command.
It seems so obvious, no one talk about it.

Thanks for your help

The file can be anywhere, you just pass it along as the argument to -P.

with anywhere you mean anywhere on disk ?

Let say I would like to build a tool to override material of all objects in myscene with a materail choosen from a menu ? What should be my options ?

PS : Forget it.
After a good night, I get it to work.

Regarding this script I have a new question.

Is it possible with an exernal script, to read node property ?
More specifically, how the script called by the mantra command could be able to read properties of the mantra ROP.
I would like to knowif it is possible to change the script behavior with node parameters.

Thanks
