MEL command to set Render Settings Image Format using Arnold

jen_steinkamp — Sat, 07 Jan 2023 22:23:31 GMT

I can change the "Maya Software Render" "Render Settings" Image Format to tif using this MEL command:
setAttr "defaultRenderGlobals.imageFormat" 3;
This command does not work for Arnold.

I would like to do the same for defaultArnoldRenderGlobals.

Any suggestions?

These examples do not seem to work, I tried this MEL script, the python does not work as well:

setAttr "defaultArnoldDriver.ai_translator" -type "string" "jpeg";
// Error: line 1: setAttr: No object matches name: defaultArnoldDriver.ai_translator

Those script commands work in a default scene with the default Arnold nodes. You can just update the commands with the names of the driver nodes in the scene.

I tried a default scene and resetting to default Render Settings; I also tried creating new prefs for Maya.

I am using Arnold 5.2.2.1

print( getAttr( "defaultArnolddriver.ai_translator" ) + "\n");
// Error: line 1: No object matches name: defaultArnolddriver.ai_translator

"dd" should be "dD" in the above

I'm using MtoA 5.2.2.1
