You need to use the shader name that you see in an ASS file.

That won't be ../matnet/body/OUT_material, it will be something like

/obj/matnet1/arnold_materialbuilder1/standard_surface1

Please check a Debug-level Arnold log. That will show operator-related messages.

Most likely the selection expression is wrong.

For testing, try a different selection. Like one specific object, or all polymeshes
