Hello, just a desperate quickie
I need to change the imageformat output of a load of scenes to EXR (Multichannel), and I’m having trouble doing so with mel.
setAttr "vraySettings.imageFormatStr" 6; // Error: line 1: setAttr: 'vraySettings.imageFormatStr' is not a simple numeric attribute. Its values must be set with a -type flag. //
I try the “-type” flag to string and while I get no more error, it doesn’t appear to change the format 
.
I must be missing something super-obvious, but again I’m pushed for time before a long weekend here. Any advice most welcome 
Hi,
The correct command is: setAttr “vraySettings.imageFormatStr” -type “string” “exr (multichannel)”;
If you want to get the value you have to use in the setAttr command you can use this command: print(`optionMenuGrp -q -v vrayImageFormatMenu`);
Execute the command after you’ve set the desired value in the combo box in the render settings.
Then you can copy paste it in the set command.

Ahh thank you Teodor.
It was indeed a silly oversight of mine.
setAttr “vraySettings.imageFormatStr” -type “string” “6”; is what I was trying.
Thank you as always for the outstanding support!
