Arnold environment variable for disabling "autodetect threads"?

[Anonymous]

Is there an environment variable that can be set to DISABLE the "Autodetect Threads" checkbox?

(Maya 2017, Arnold 5 (MtoA 3.1.1))

Okay. When i open a Fresh maya application, the auto tx convert option should stay disabled by default. What is the best way to do this?

This userSetup.py disables autotx:

import mtoa.hooks
 
def setupOptions(options):
	cmds.setAttr('{}.autotx'.format(options), 0 );

mtoa.hooks.setupOptions = setupOptions

@Stephen Blair Thank you man. It worked. I put the the script in my usersetup.py file and added defalutArnoldRenderOptions, It is working now. Thanks again.
