3dsmax substance plugin keeps resetting to GPU mode.

Hi,

We have render nodes on our farm that do not have GPUs.  This results in us not being able to render anything with substance on our farm.  I have set CPU mode manually and confirmed the setting stuck after re-launching max, but when deadline launches a job it somehow resets this mode.  I am able to get it to work if I currently have a max instance open with CPU mode on, but as soon as I close max and launch deadline it resets to GPU.

If there is a way around this I would love to hear it.  My initial thought on how to get around this is to setup a startup script in max that changes substance to CPU mode, but I am unable to find the maxscript command for this and the maxscript listener doesn't show one when swapping.

Does anyone know a way to force CPU mode on launch?

Thank you
