Nested stand-ins with StringReplace operater cannot be found

[matthias.richter]

We're heaviliy using the StringReplace operator in order to render stand ins that we created on workstation running Windows on our Linux based render farm. Works like a charm.

I ran into trouble when exporting an ass-file that contains stand-ins itself. Seems when rendering the scene with Maya in batch on the farm the operator does not replace the string in the "lower-level" stand-ins and thus they won't be found.

It works with kick, though.

Help is appreciated.

What strings are replacing? Something the image.filename?
Just so I know what to test

Yes, I'm replacing the string in the .dso attribute of stand-ins.

Here's my code to create the actual operator:

from pymel.core import *

n0 = createNode("aiStringReplace", n="Standin_Path_Switch")
n0.selection.set("*.(@node =='materialx')")
n0.os.set(1)
n0.match.set("[wW]:/")
setAttr(str(n0)+".replace", "/")
n0.out >> SCENE.defaultArnoldRenderOptions.operator

I've tried with standins and alembics, and so far it's worked.

I'm doing a string replace on procedural.filename or alembic.filename.

This is with MtoA 4.2.2.0 on Windows 10.

The nesting is two and three levels deep.

Can you get a debug Arnold log from a farm machine? That way we can at least check that the operators are matching something...

Thanks
